Do you have a heater contactor for running (2) 1500 Watt, 240 VAC heaters ? Need (2) contactors each rated for 10 or 15A, in an enclosure.

Asked by: Iceman
Hi Iceman, Thank you for the inquiry. Our control relays are currently limited to 10 A service; https://br.omega.com/omegaFiles/auto/pdf/XTRE_SERIES.pdf https://www.omega.com/en-us/communication-and-connectivity/interface-cards/electromechanical-relays/xtre-series/p/XTRE10B40A Best regards OMEGA

omega recommend a cm16d3-m-ac controller how do i hook up wires to retransmit temperature signal to a plc

Asked by: james o
The output of this controller is a 'powered output' so simply run terminal # 5 (+) to the Positive input of your PLC, and #4 (-) to the Negative input of your PLC.

On the manual it lists the factory setting for the temperature lower limit is -200C, does that mean that it can accurately measure values at -200C and then heat up to room temperature? We are trying to use this controller with a low temperature system.

Asked by: Finn1384
This unit can control process temps to -200 C accurately if the sensor accuracy is compatible with the temperature range as well. Example of compatible sensor is the PT100 RTD. And example probe is ; PR-11-2-100-1/8-12-E Thank you for your question.
