A. Motherboards DP20000-x, base price from
(Power and display preferences refer to the DP2000 ordering guide.)
Choose the appropriate OMEGA®motherboard. The motherboard constitutes the complete DPM electronics and power supply for any combination of inputs and outputs.
All power supplies provide cool operation, resulting in extended component life. The AC-powered versions use a high-efficiency power transformer, and the isolated 9 to 32 Vdc versions maintain display brightness over the entire voltage range. A non-isolated 5 Vdc version is also available.
Signal input and power connections are made via a rear barrier terminal strip. The motherboard rear edge connector provides access to hold and display test, polarity, clock, and the standard 1 mV/count analog output and optional analog outputs. Decimal point position can be selected by jumpers on the edge connector or by placement of gas-tight jumpers behind the front lens.
Ordering Example: DP2100-J1, LCD, 120 Vac motherboard with J thermocouple signal conditioner input, $275 + 80 = $355.

B. Analog Outputs DP20000-x
In addition to the standard OMEGA® analog output of 1 mV/count, 6 optional outputs are available:
1. 0 to 5 Vdc $70
2. 0 to 10 Vdc 70
3. 0 to 1 mA (Internally Driven) 70
4. 4 to 20 mA (Internally Driven) 70
5. 4 to 20 mA (Externally Driven) 115
6. 4 to 20 mA (Isolated) 135
Both DC voltage outputs drive up to 2 mA. The internally driven 4 to 20 mA output drives up to 600 (12V compliance), while the externally sourced 4 to 20 mA output can be driven by 5 to 40 Vdc. The user has access to the analog output at the motherboard edge connector.
Ordering Example: DP2010-A1, LED, 120 Vac motherboard, 0 to 5 Vdc analog output with ±0.1999 Vdc input, $225 + 70 + 40 = $335.
Add to Base Price:
C. Control Outputs DP20000-x
For capabilities beyond simple indicating, choose from 5 OMEGA®control outputs: a dual-setpoint on/off controller, a proportional 4 to 20 mA controller, a proportional plus time-proportioning controller, a parallel BCD output, or a single-setpoint on/off controller. Controllers feature convenient quick-connect terminals with mating connectors supplied. The parallel BCD outputs to a 50-pin edge connector.
1. Dual-Setpoint Controller, add
The OMEGA®dual-setpoint controller features 2 internal relays controlled by high/low setpoint adjustments accessible through the front lens. These screwdriver-adjustable setpoints can be used for limit alarm functions, on/off control, 2-position differential control, 3-position control, and limit-cycle control.
The low setpoint is adjustable over the entire -1999 to 1999 display range. The high setpoint is adjustable in the range between the selected low setpoint and 1999. Either setpoint can be displayed by pressing the low or high setpoint pushbutton on the front panel.
Both relays are de-energized when the input value (measured variable) is between the low and high setpoints. When the input value falls below the low setpoint, the low relay energizes. When the input rises above the high setpoint, the high relay energizes.
Red “LO” and “HI” lamps on the front panel light when their respective relays are energized. All relays are rated 10 A @ 120 Vac and 240 Vac.
Ordering Example: DP2001-A2, LED motherboard, dual-setpoint controller with ±1.999 Vdc input, $225 + 165 + 40 = $430.
2. Proportional 4 to 20 mA Controller, add
The OMEGA®proportional controller provides a 4 to 20 mA output in proportion to the difference between the input and the selected setpoint value. The screwdriver-adjustable setpoint, accessible through the front lens, can be set for any value within the -1999 to 1999 display range. The setpoint or the deviation of input from setpoint may be displayed by pressing front-panel pushbuttons.
The controller features adjustable proportional band (1 to 10%) and a front-panel LED that lights when the input (process) is within this band.
The 4 to 20 mA output provides 12V compliance, or it can be connected to use an external source
for up to 35V compliance.
Ordering Example: DP2002-P9, LED motherboard, proportional 4 to 20 mA controller with 4 to 20 mA input, $225 + 225 + 60 = $510.
3. Proportional Plus Time-Proportioning Controller, add
This controller provides all the features of a proportional controller, plus a time-proportioning solid state relay output for on/off cycling control.
Two red LEDs on the front panel indicate when the relay is energized and when the process is within the proportional band. A screwdriver adjustment, accessible through the front lens, lets the user adjust the manual reset over 100% of the proportioning band. A front-panel pushbutton switch allows display of the input parameter or the amount of deviation from setpoint. Logic inputs allows reversing of the sense of the relay or the relay LED. All relays are rated 2 A @ 240 Vac.
Ordering Example: DP2003-P9, LED motherboard, proportional/time proportioning control with 4 to 20 mA input, $225 + 295 + 60 = $580.

4. Parallel BCD Output*, add
For users with digital data acquisition needs, this option provides buffered, isolated (350V), gated, and stored BCD outputs on 14 parallel lines plus 2 lines for polarity and data-ready. All buffers have 3 stateoutputs for easy parallel bussing in data acquisition systems. Inputs and outputs are 5 Vdc TTL logic, positive true logic only. A BCD HOLD input holds the BCD data stored in the latches, but allows the instrument to continue making updated conversions.
Along with broadside parallel outputs, this option allows the transmission of 8 bits of data at a time for devices with 8-bit data paths such as computers. A 5V @ 100 mA power supply is necessary to use the BCD output.

5. Single-Setpoint Controller, add
The single-setpoint controller board features one internal form “C” relay, rated to 10 A @ 30 Vdc or 240 Vac, resistive load. The setpoint is front-panel adjustable over the entire display range. The setpoint provides adjustable deadband to limit relay cycling or chatter. Pushbuttons are conveniently mounted on the front panel, and the LED lamp provides on/off status of the relay.

* Note: A power supply is required when ordering a parallel BCD output card.
Ordering Example: DP2004-K2, LED motherboard, BCD output with Type K thermocouple input, PST-5, power supply, $225 + 155 + 80 + 165 = $625.
Fail-Safe Control Mode:
In this mode, the relay is energized when the meter input is below the setpoint. When the input rises above the setpoint, the relay is de-energized. In the event of a power failure, the relay is de-energized, signaling an alarm condition.
Latched or Non-Latched Operation:
The controller can be configured so that the relay is latching. In latched operation, the relay remains energized until the alarm condition is acknowledged either by pressing both front-panel pushbuttons simultaneously or by momentarily closing an external switch tied to a RESET input.
Add the OMEGA®signal conditioner that matches the sensor and process variables. OMEGA®will configure the range the user selects, which can be changed later via a “pin-forest” of gas-tight, movable internal jumpers. Fine calibration is effected with zero and full scale adjustments on the left side of the display behind the lens. All signal input connections are made via barrier screw-terminal strips.
Ordering Example: DP2005-P9, LED motherboard, single-setpoint controller with 4 to 20 mA input, $225 + 125 + 60 = $410.

2: Determine gain = full scale span
3: Find ordering code for which desired gain lies
between minimum and maximum values listed.
4: Use ordering code to complete part number.
Ordering Example:
Signal Range: 0.5 to 5.5V (5V span) Full scale display: 100.0 psi (1000 counts) Gain = 1000 counts
Choose P4 because 8 < 200 < 231 To Order, specify DP2000-P4, $285. Model P is designed for use with OMEGA
cells and strain gage devices.

required (max reading – min reading)
2: Determine gain = full scale span
3: Find ordering code for which
desired gain lies between minimum and maximum values listed.
4: Use ordering code to complete
part number.
Ordering Example: (Part A—Gain Determination)
Input signal range: 0 to 100 mV Full scale display: 500 psi (500 counts) Gain = 500 counts
Choose S1 because 4.01 < 5 < 9.9
