DESCRIPTION:
The X54-3402 is a dual channel RTD alarm trip
powered by 24 vdc. Features include: two piece plug-in connectors for
easy wiring and maintenance; Power/Sensor Fail LEDs; field configur-
able ranges and RTD types; 1000 vac isolation; and front panel
ZERO, SPAN, and setpoint adjustments. RFI protection, wide operat-
ing temperature, and high accuracy are standard. Dual setpoints are
user configured for high or low and have adjustable deadband. Output
relays are form “C” and can be normally energized or de-energized.
Custom inputs, outputs, and scaling are available from the factory.
