SERIES SC1
PROCESS/TEMPERATURE ALARM SWITCH MODULE
Two Form C (SPDT) Switches, Small Size, Mounts Easily on 35 mm DIN Rail
PROCESS CONTROL
The Series SC1 Process/Temperature Alarm Switch Module is an on-off or limit
switch with selectable process signal. Each unit has two form C (SPDT relays which
can operate independently, or be logically connected to operate as a DPDT output.
BENEFITS/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
APPLICATIONS
• Stand alone CO monitoring in parking garage
• Industrial processing equipment
