Introduction

Section 1 - Introduction

The DP606A/DP612A Display Meter offers a flexible, easy to use 6 or 12 zone, 4 digit
temperature and process measurement solution in a rugged ¼ DIN Aluminum
housing. Selectable configuration eliminates the need for jumpers.

The DP606A supports 6 independent zones and the DP612A supports up to 12 zone
(3 wire RTD limited to 6 zones on all models). All zones are scanned at a 400ms rate.
The display shows the reading of each zone sequentially. High and low Alarms with
SPDT relay outputs are available for monitoring and alarm purposes.

The universal input supports 9 thermocouple types (J, K, T, E, R, S, B, C, and N), 2 or
3 wire RTDs (Pt 100, Ni 120, Cu 10), DC voltage (0-1 Vdc), or DC current (0 – 24 mA).
Independent alarms are available for each zone. Each alarm can be configured for
above (HI), below (LO) or HI/LO triggering. Alarms conditions will be indicated on
the display meter and may be used to activate either of the 2 SPDT relay outputs.

A user selectable RS232 or RS485 serial port interface is standard on all models and
uses the Modbus RTU protocol for configuration management and data transfer.

The universal AC power supply accepts 90–240 Vac. The isolated DC power option
accepts 9–36 Vdc.

A security password can be used to prevent front panel tampering of the
configuration.

The instrument is a device protected in accordance with UL 61010:2010 Electrical
Safety Requirements for Electrical Equipment for Measurement, Control and
Laboratory. The device has no power-on switch. Installations must include a switch
or circuit breaker that is compliant to IEC 947-1 and 947-3. It must be suitably
located to be easily reached and marked as the disconnecting device for the
equipment.

WARNING: Do NOT connect AC power to your device until you have completed
all input and output connections. This device is a panel mount device protected in
accordance with Class I of EN 61010 (115/230 AC power connections), Class III for
the DC power option (9-36Vdc). It must be installed by a trained electrician with
corresponding qualifications. Failure to follow all instructions and warnings may
result in injury.

Use Copper conductors only, minimum 20 AWG, UL Rated, for power and outputs.
Insulation must be rated for at least 85ºC and 600V.

This device is not designed for use in, and should not be used for, patient-connected
applications.

Safety:

EMC:

WARNING: Failure to follow all instructions and warnings is at your own risk and
may result in property damage, bodily injury and/or death. Omega Engineering
is not responsible for any damages or loss arising or resulting from any failure to
follow any and all instructions or observe any and all warnings.

• Do not exceed the voltage rating on the label located on the device housing.

• Always disconnect power before changing signal and power connections.

• Do not operate this instrument in flammable or explosive atmospheres.

• Do not expose this instrument to rain or moisture.

• Whenever EMC is an issue use shielded cables.

• Never run signal and power wires in the same conduit.

• Use signal wire connections with twisted-pair cables.

• If EMC problems occur Install Ferrite Bead(s) on signal wires close to the
instrument.

CAUTION: Risk of electric shock. Disconnect all power sources before servicing.

Mounting Instructions

Section 3 - Mounting Instructions

Select a location for the monitor that is free from excessive shock, vibration, dirt,
moisture and oil. Mount the monitor into a 3 5/8” (92mm) square cutout. The
monitor as shipped is 1/4 DIN (92mm square), so it does not have to be removed
from its housing to be mounted. Remove the two screws that secure the mounting
slides. Remove the slides and insert the case into the cutout from the front side of
the panel. Reinstall the two slides and two screws. The length of the slides must be
reduced if the monitor is to be mounted in an extra thick panel.

Ensure that the unit is properly grounded to the panel which should be earth
grounded. Use the supplementary ground point indicated on the rear panel if a
good ground connection cannot be maintained from the mounting slides alone.

Table 2 - 9-Pin Input Power/Relay Wiring Summary

Connect the main power connections to pins 4 and 9 (AC Power) or pins 5 (+) and 9
(-) (DC Power) of the 9pin power / output connector as shown in Figure 3.

Figure 3 - Main Power Connections

For the low-voltage power option, maintain the same degree of protection as the
standard high-voltage input power units (90–240 Vac) by using a Safety Agency
Approved DC source with the same Overvoltage Category and pollution degree as
the AC model.

The Safety European Standard EN61010-1 for measurement, control, and laboratory
equipment requires that fuses must be specified based on IEC127. This standard
specifies the letter code “T” for a Time-lag fuse.

The DP606A/DP612A Series includes SPDT mechanical relays with internal
snubbers on the normally open contact side. When powered and not in an alarm
state the relays are Energized and the NO contact is connected to the Relay
common contact. If an alarm condition occurs or if the unit loses power the relay is
deenergized and the NC contact is connected to the Relay common contact.

WARNING: For the low-voltage power option, maintain the same degree of
protection as the standard high-voltage input power units (90–240 Vac) by using a
Safety Agency Approved DC or AC source with the same Overvoltage Category and
pollution degree as the standard AC unit (90–300 Vac).

Table 3 - Connecting Communications

Note: The RTN signal is isolated from the Signal RTN and the Power GND.

Section 4.5 - Connecting Inputs

Connect Input sensors to the terminals Marked Zone 1 though Zone 12 (Z1 – Z12) on
the rear panel. For the DP606A only Zones 1 through 6 are active and Terminals Z7
– Z12 are only used for 3 Wire RTDs. When connecting sensors follow the polarity
indicated on the rear panel. For Thermocouples the Negative wire is Red (NA) or
White (IEC 584-3). For Process Inputs the Negative terminal is ground.

For the RTD 3 wire option the common wires must be connected to the + terminals
of both the upper (Z1 – Z6) and lower (Z7 – Z12) input boards. The negative terminal
of Z7- Z12 remains unconnected. If a 2 wire RTD needs to be used in 3 Wire mode
use a jumper wire to connect the upper and lower terminals together. Refer to the
wiring diagram below.

Note that all negative input terminals share a common internal ground connection.
Ensure that all sensors share a common ground or are fully isolated.
