Series SC1 Process/Temperature Alarm Switch Module

Brand: Dwyer Instruments, LLC
Request Information
The Series SC1090 Thermocouple Limit/Alarm Switch Modules are on-off or limit switches with selectable process signal.

Input type, scale range, output action, and output type are all selectable by the user in the field.

All selections are made through easily accessible switches without the need to open the product. Each unit has two form C (SPDT) relays which can operate independently, or be logically connected to operate as a DPDT output.

A two color LED indicator indicates the status of each output relay.

These units mount easily on a standard 35 mm DIN rail. Low Voltage (SCLXXXX) units are also available.
Features
  • Accepts Current, Voltage, Thermocouple, or RTD Inputs
  • Mounts on Standard 35 mm DIN Rail
  • Two color LED indicator to indicate the status of each output relay
  • Programmable input type, scale range, output action, and output type
