Features:
- Accepts three-wire Pt100, JPt100 or Pt50 resistance sensors.
- Produces two standardized 1 to 5 V DC output channels.
- Separates the field input from output, power and ground circuits.
The C-style card is configured for resistance-temperature measurement rather than millivolt or current input.
It excites, linearizes and isolates the RTD signal before delivering system-level voltage outputs.
Sensor curve, span links and lead compensation must be verified against the installed element.
Apter Power can review sourcing, documentation and system matching for ER5*C.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Temperature loops from vessels, bearings and heat exchangers can be standardized for CENTUM input processing.
- Dual outputs allow the conditioned value to serve separate monitoring and control destinations.
- Legacy panels can retain existing RTD field wiring when the exact card style and range arrangement are preserved.
- Selectable ranges cover the supported Pt100, JPt100 and Pt50 sensing elements.
- Ambient operation is specified from 0 to 50 °C for the installed card.
- Range selection must follow the actual sensor curve and required process span.
- The RTD input is isolated from the two voltage outputs.
- Power and ground separation reduces unwanted current paths through the measurement loop.
- Isolation does not replace correct shielding and cabinet grounding practices.
- A known resistance source can verify the configured temperature span.
- Three-wire lead continuity should be confirmed before zero and span checks.
- Both 1 to 5 V outputs should track the same simulated RTD points.
