SNAP Analog Input Modules

Part Numbers

DESCRIPTION

SNAP I/O analog input modules are part of Opto 22’s SNAP PAC System. All of these modules mount on a SNAP PAC rack with a SNAP PAC brain or R-series controller, either a standard wired model or a Wired+Wireless™ model.

A minimum number of SNAP module types support a full range of analog input requirements. These software-configurable modules handle a wide variety of signal levels. They provide high resolution (0.004% of nominal range) for precise signal levels, as well as multiple-channel packaging. All SNAP analog modules are factory calibrated and individually tested. Part numbers ending in -FM are Factory Mutual approved.

SNAP analog input modules have an on-board microprocessor to provide module-level intelligence, which makes them an ideal choice for Original Equipment Manufacturers (OEMs). For additional information about the standalone operation of SNAP analog modules, see Opto 22 form #0876, SNAP I/O Module Integration Guide.

Notes for legacy hardware: Some of these modules also work with older Opto 22 I/O processors (brains or on-the-rack controllers) and M-series or B-series racks. To check processor compatibility, see the table on page 3.

Specifications begin on page 4. For dimensional drawings, see pages 40–51.

IMPORTANT: Any system using analog sensors and input modules should be calibrated annually for analog signals. For I/O units on a SNAP PAC System, use the PAC Control™ commands “Calculate and Set Offset” and “Calculate and Set Gain.” For other Ethernet-based I/O units, you can also use PAC Manager™ software to calculate and set offset and gain.

Isolation

All SNAP analog input modules are isolated from all other modules and from the SNAP I/O processor. The modules

in this data sheet do not have channel-to-channel isolation, however. (If you need isolated analog modules, see Opto 22 form #1182.)

Transformer isolation prevents ground loop currents from flowing between field devices and causing noise that produces erroneous readings. Ground loop currents are caused when two grounded field devices share a connection, and the ground potential at each device is different.

Isolation also protects sensitive control electronics from industrial field signals.

IMPORTANT: Since these analog input modules provide multiple single-ended input channels with a common reference, the channels are not isolated from each other. (See Opto 22 form #1182 for isolated modules.)

Bipolar and Unipolar Input Modules

Most SNAP analog input modules are considered to be bipolar, which means the range extends equal amounts above and below zero. An example of this is the SNAP-AIV module, which has a range of -10 to +10 VDC.

Some modules are considered unipolar, which means the range starts or ends at zero. For example, the SNAP-AIVRMS module has a range of 0 to 250 VAC because AC current cannot be negative.

Nominal Range and Over-range Limits

All SNAP analog input modules have a nominal range for the field signal and most support a 10% over-range limit. The nominal range is the normal range of the field signal for the module or point configuration. The over-range limit is the maximum valid field signal the module or point configuration can read outside of the nominal range. For example, the over-range limits for the SNAP-AIV are -11 and +11 VDC, and for the SNAP-AIVRMS, the over-range limit is 275 VAC.

Some modules or point configurations do not support field signals outside of the nominal range. For example, points configured as temperature inputs (thermocouple, RTD, ICTD) do not support over-range readings.

When the field signal is outside of the over-range limits of the module, the brain will not be able to determine if the value is too high or too low, so it will return an "out of range" value of -32768.0

Over-range limits only apply to input modules. Output modules are limited to their nominal ranges.

1. Place the rack so that the module connector numbers are right-side up, with zero on the left, as shown in the diagram above. (If your rack has screw connectors, the screw connectors will be at the bottom.)

2. Position the module over the module connector, aligning the small slot at the base of the module with the retention bar on the rack. When positioning modules next to each other, be sure to align the male and female module keys at the tops of the modules before snapping a module into position.

3. With the module correctly aligned, push on the module to snap it into place.

4. Use standard 4-40 x 1/2 truss-head Phillips hold-down screws to secure both sides of each module.

CAUTION: Do not over-tighten screws. See Specifications.

5. Follow the wiring diagrams beginning on page 4 to attach

modules to the devices they monitor. Most modules accept 22 to 14 AWG wire; the SNAP-AITM-8 accepts a maximum of two solid 18 AWG wires.

For faster, easier field wiring installation and maintenance, use SNAP TEX cables and breakout boards. See Opto 22 form #1756, the

SNAP TEX Cables & Breakout Boards Data Sheet, for compatibility and specifications.

Wiring

SNAP TEX cables and a breakout rack are available separately for wiring points to field devices (see form #1756, the SNAP TEX Cables & Breakout Boards Data Sheet). The SNAP-HD-BF6 cable connects the module to the breakout rack, which can then be wired to field devices. (NOTE: The SNAP-HD-CBF6 wiring harness with flying leads is not recommended for this module.)

CAUTION: We strongly recommend that you use the breakout rack with these modules. Miswiring of any point on the module can cause severe out-of-warranty damage. The breakout rack protects the module from many wiring errors.

if you are using the module with loop power (2-wire) negative common devices, connect to the SNAP-AIMA-HDB (or -FM) rack. If you are using the module with self-powered devices (4-wire) or with devices that share a common positive connection, do not use the SNAP-AIMA-HDB (or -FM) boards, which have a current limiting diode. Instead, wire to the SNAP-AIV-HDB or SNAP-AIV-HDB-FM.

Correcting for Inverted Scaling

Positive readings for these modules appear as negative values. Therefore, in order to obtain meaningful readings, use the scaling feature in PAC Control as follows:

1. In the Add or Edit Analog Point dialog box for each point, choose the scalable version of the module.

2. Under Scaling, scale each point negatively as shown below:

SNAP-AIR400K-8

Description

The SNAP-AIR400K-8 module has eight channels of analog to digital conversion that convert resistance to temperature or to Ohms. The module is ideal for NTC thermisters commonly used in HVAC, refrigeration, and process control applications. It may also be used with PTC thermisters in resistance sensing applications. See the table on page 3 for I/O processor compatibility.

The SNAP-AIR400K-8 reads variable resistance type transducers, and it has 12 resistance input ranges from 500 Ohms to 400 K Ohms, plus Autorange. Range dependent resolution is from 20 milliOhms to 16 Ohms.

SNAP PAC brains and PAC Control provide direct temperature readings for four popular thermistors using the Steinhart-Hart equation (see

page 19). You may also enter custom coefficients for other thermistor

curves.

The simple two-wire connections are made to the pluggable terminal strip on top of the module.

NOTE: The eight input channels must be electrically isolated from each other and earth ground. The transducer resistor element must be isolated from any electrically conducting probe tube housing.

Predefined Curves

The following table shows temperatures in °C and °F that correlate with resistance values in Ohms for the generic curve types for four popular thermistors using the Steinhart-Hart equation. Choose the curve type for your application in PAC Control or PAC Manager when you configure a SNAP-AIR400K-8 module. (For custom curves, see

Choose a 2-wire thermistor value with a resistance over the target temperature range that is much larger than the lead resistance for your application

Lower value curves (2252 or 3K) work best at cooler temperatures (< 25 °C or 77 °F) because long lead wire resistance can add significant errors to the measurement.

RTD INPUT MODULES (CONTINUED)

SNAP-AIRTD-8U

Description

The SNAP-AIRTD-8U provides 8 input channels, each individually software configurable. This module is commonly used for 3-wire RTD temperature inputs but is also suited to high-resolution resistance measurements. It features open circuit detection if any wire breaks.

All 8 inputs share the same reference terminal. Make sure you use isolated RTD probes.

The SNAP-AIRTD-8U requires a SNAP PAC brain or R-series controller with firmware R9.5a or higher. The module cannot be used with legacy brains or controllers.

Point Configuration

See table at right. You can individually configure each of the module’s 8 points for a variety of behaviors:

• Temperature—Range is fixed. Default range is 0–8000 ohms. Choose nickel, platinum, or copper RTD input. The data returned is degrees C or degrees F, depending on your choice for the I/O unit.

• Fixed-range (default)—Choose the range you want to use. If the value goes above the limit for that range, an out-of-range value (16-bit) of –32768 is displayed. The data returned is resistance in ohms.

• Full Auto-range—The module scrolls up and down the entire set of ranges and dynamically chooses the appropriate range for best resolution. Note that this point type can result in higher latency when ranging up (see Specifications on next page). The data returned is resistance in ohms.

• Auto-range Down—The module scrolls down and up within the specified range limit. If the value goes above the specified range, an out-of-range value (16-bit) of –32768 is displayed. These point types allow auto-ranging within the selected range but limit the data latency when ranging up. The data returned is resistance in ohms.

Wiring

The SNAP-AIRTD-8U has a plug-in terminal on top with spring-clamp connectors for easy wiring. An insertion tool is provided in the box with the module.

For each connection:

1. Insert the tool in the small square hole and push down.

2. Push the wire firmly into the rectangular hole below the tool, and

then remove the tool.

The module is designed for 3-wire RTDs, shown below. All wires must be the same size. If you use a 4-wire connection, DO NOT connect the fourth wire, as it will cause errors in the readings. If you use 2-wire RTDs (not recommended because measurement is less accurate), you must jumper terminal 2 to 3 for each applicable RTD channel.

Older products

From solid state relays (our first products) to world-famous G4 and SNAP I/O, to SNAP PAC controllers, older Opto 22 products are still supported and still doing the job at thousands of installations worldwide. You can count on us to give you the reliability and service you expect, now and in the future.

QUALITY

Founded in 1974, Opto 22 has established a worldwide reputation for high-quality products. All are made in the U.S.A. at our manufacturing facility in Temecula, California.

Because we test each product twice before it leaves our factory rather than testing a sample of each batch, we can afford to guarantee most solidstate relays and optically isolated I/O modules for life.

groov EPIC Processor

The heart of the system is the groov EPIC processor. It handles a wide range of digital, analog, and serial functions for data collection, remote monitoring, process control, and discrete and hybrid manufacturing.

In addition, the EPIC provides secure data communications among physical assets, control systems, software applications, online services, and more, both on premises and in the cloud.

Configuring and troubleshooting I/O and networking is easier with the EPIC’s integrated high-resolution color touchscreen. Authorized users can manage the system locally on the touchscreen or on a monitor connected via the HDMI or USB ports.

groov EPIC Software

Software included in the groov EPIC controller:

• PAC Control engine to run PAC Control strategies and PAC Display projects

• CODESYS Runtime engine to run IEC61131-3 compliant programs built with CODESYS Development System
