GuardPLC 1753-IF8XOF4 Analog I/O Module 7

Wire the Module

Ground the Module

You must provide an acceptable grounding path for each device in your application. For more information on proper grounding guidelines, refer to the Industrial Automation Wiring and Grounding Guidelines, publication number 1770-4.1.

The I/O module is functionally grounded through its DIN rail connection. A protective earth ground connection is required and is provided by a separate grounding screw, located on the upper left of the housing and marked with the

grounding symbol .

ATTENTION

This product is grounded through the DIN rail to chassis ground. Use zinc plated yellow-chromate steel DIN rail to assure proper grounding. The use of other DIN rail materials (e.g. aluminum, plastic, etc.) that can corrode, oxidize, or are poor conductors, can result in improper or intermittent grounding.

Connections for Safety-Related Communications

Ethernet Switch

The module has two 10/100BaseT, RJ-45 connectors, located on the bottom of the unit, that provide communications to the GuardPLC controller via GuardPLC Ethernet. Because this is an Ethernet switch, you can daisy-chain connections from the GuardPLC to other distributed I/O blocks. The switch is auto-detect. Either cross-over or straight-through shielded Ethernet cabling can be used.

Star or line configurations are available. Make sure that a network loop is not generated. Data packets must only be able to reach a node via a single path. Ring topology is not supported.

MAC Address

The Media Access Control (MAC) Address of the module can be found on the label positioned over both lower RJ-45 connections.

Publication 1753-IN013A-EN-P - September 2005

8 GuardPLC 1753-IF8XOF4 Analog I/O Module

Connect the Voltage Supply

The 24V dc voltage supply must feature galvanic isolation (in accordance with EN 60950 or UL 1950) since inputs and outputs are not electrically isolated from the internal processor. In order to comply with CE Low Voltage Directives (LVD), you must use either a NEC Class 2, a Safety Extra Low Voltage (SELV) or a Protected Extra Low Voltage (PELV) power supply to power this module. A SELV supply cannot exceed 30V rms, 42.4V peak or 60V dc under normal conditions and under single fault conditions. A PELV supply has the same rating and is connected to protected earth.

IMPORTANT

The supply voltage is connected via a 4-pin connector.. You only need to connect one wire to L+ and one wire to L-. Both L+ and L- terminals are internally connected, so you can daisy-chain 24V dc power from the GuardPLC to other devices in the panel using the remaining terminal. See the wire size and terminal torque specifications on page 16

ATTENTION

Protect the module with a 10 A slow-blow fuse.

Do not reverse the L+ and L- terminals or damage to the module will result. There is no reverse polarity protection.

Safety Analog Inputs

The module has 8 analog inputs with sensor supplies for the unipolar measurement of voltages from 0 to 10V. A 10 kΩ shunt is used for single-ended voltage signals. With a 500 Ω shunt resistor, currents from 0 to 20 mA can also be measured.

Publication 1753-IN013A-EN-P - September 2005

GuardPLC 1753-IF8XOF4 Analog I/O Module 9

Analog cabling should be no more than 300 m (984 ft) in length and must be shielded, twisted-pair cables for each measurement input. The shields must be connected at one end.

IMPORTANT

Short-circuit unused input channels to the reference pole by connecting wire jumpers.

(2)

Voltage Measurment

If an open-circuit fault occurs during voltage measurement, unpredictable input signals are received on the high resistance inputs. Values resulting from this fluctuating input voltage are not reliable. Because the module does not feature circuit monitoring, you must terminate input channels with a 10 kΩ resistor when measuring voltage. Consider the internal resistance of the source as well.

Current Measurement

To measure current, connect a 500 Ω external shunt in parallel to the input. Accuracy of the shunt must be included in accuracy calculations of the input signal. Terminating resistors are not required for current measurement with the external shunt connected in parallel.
