COPELAND 800-2100 Pressure Transducer Installation Guide
Description
This bulletin provides technical information about Copeland pressure transducers.
Cautions, Warnings, and Notices
- CPC transducers require +5VDC power to operate. DO NOT connect this transducer to +12VDC power. Doing so will damage the transducer and void the warranty.
- Previous transducer models required installation techs to set the input type dip switch to the DOWN position on input boards. The below transducers require you to set the input type dip switch to the UP position.
Part Numbers
Table -1 lists the part numbers for all pressure transducers currently available from Copeland, including the part numbers.

Hardware Specifications
Supply Voltage
Transducers (800-2100, 800-2101, 800-2200, 800-2201, and 800-2500, 800-2501,
800-2651, 800-2711, 800-2721) require an excitation voltage of +5 VDC. This is
NOT the same voltage required by the old “standard” transducers, which
required +12 VDC.
Important! Do not connect the CPC transducer to +12 VDC. Doing so will damage the transducer and void the warranty.
Operating Temperature Range
The transducers are rated to withstand ambient temperatures from -22°F to 158°F (-30°C to +70°C), and media (refrigerant) temperatures from -40°F to 300°F (-40°C to 149°C).
In ambient temperatures from +90°F to +160°F (+32°C to +71°C), the maximum allowable media temperature is derated from +300°F (149°C) by 2° for every one degree that ambient temperature is above +90°F (+32°C)
Output Signal
The transducer’s output signal voltage varies from 0.5 to 4.5 VDC as the pressure varies from zero to the transducer’s maximum value. When the transducer reads a pressure that is above 110% of its maximum rating, the signal voltage will stop at ~4.9 VDC.
The maximum error between the measured pressure and the pressure signified by the output signal voltage is ±1.5%. This means the output signal will have a maximum error of ±1.5 PSI for the 100PSI transducer, ±3 PSI for the 200PSI transducer, and ±7.5 PSI for the 500PSI transducer.
Fittings
All transducer male and female models have 1/8” NPT fittings. If replacing a standard transducer with 1/4” SAE port and Schrader depressor, the valve fitting will have to be replaced by a female 1/8” NPT port.
Note: On request, Copeland can supply replacements for “standard” transducers equipped with a female 1/4” SAE port with Schrader depressor. Contact Copeland if you require such a transducer.
Transducer Cable
Transducers are supplied with a 20’ cable for connecting the transducer to +5VDC power and an input board point. The cable plugs in to the top of the transducer using a Packard Metri-Pack 12065287 cable connector.
Over pressure , Burst Pressure, and Vacuum Pressure
Table -2 gives the overpressure, burst pressure, and vacuum pressure PSI ratings for each transducer model.
The overpressure rating is the PSI which, when exceeded, will cause the transducer to function incorrectly.
The burst pressure rating is the highest PSI the transducer can withstand without leaking or breaking.
The vacuum pressure is the amount of vacuum the transducer can withstand before the transducer starts to read incorrectly.
Note: The transducer will not be damaged by any amount of applied vacuum. There is no need to close transducer valves or remove transducers when applying vacuum.
Table -2 – Overpressure, Burst Pressure, and Vacuum Ratings
| Model | Overpressure | Burst Pressure | Vacuum |
|---|---|---|---|
| CPC 100PSI | 300 PSIG | 1000 PSIG | -10 PSIG |
| CPC 200PSI | 400 PSIG | 1000 PSIG | -14.7 PSIG |
| CPC 500PSI | 1000 PSIG | 2500 PSIG | -14.7 PSIG |
Installation
-
Wrap the transducer pipe fitting with Teflon tape to ensure a tight seal.
-
Screw the transducer on to the access valve. Tighten by using a wrench on the hex nut above the fitting. Do not use the transducer casing to apply torque.
-
Attach the connector of the cable harness to the port at the top of the transducer.
-
Connect the cable harness wires to the 16AI or 16AIe board as shown in Figure 1. If connection to the input board requires more than the 20’ of wire included with the cable harness, use Belden #8771 (shielded, 3 conductor, 22AWG) or equivalent to extend the cable.
Figure 1 – Pressure Transducer Installation
-
On switch S1 or S2 on the 16AI or 16AIe, set the input dip switch rocker corresponding to the input number to the UP position. This is different from the required input dip switch setting for all previous transducers. If replacing an old pressure transducer with the new pressure transducer, you must change the input dip switch setting from DOWN to UP.
Controller Programming
When setting up pressure transducer inputs in E2, E3, or Site Supervisor, set the Sensor Type to 5v-100PSI, 5v-200PSI, 5v-500PSI, 5v-650PSI, 5v-1000PSI, or 5v-2000PSI.

Table -3 lists the transducer output voltages and their corresponding pressure readings.
