Inputs

User selectable using the Model 244EC Configuration Interface and the Models 244EH and 244ER configuration software; sensor terminals rated to 42.4 V dc. See Table A-2 on page A-3.

Output

Two-wire 4–20 mA, linear with temperature for RTDs and thermocouples, and linear with input for millivolts and ohms

Isolation

Input to output isolation tested up to 500 V ac rms (707 V dc) at 50/60 Hz

Power Supply

External power supply required. The transmitters operate on 12.0 to

42.4V dc terminal voltage. Transmitter power terminals rated to

42.4V dc.
