Honeywell TC-PRR021 Redundancy Module
The Honeywell TC-PRR021 is a redundancy module designed for Honeywell C200 control system networks. It manages dual-processor failover execution, enabling real-time status monitoring and automated switchover to prevent system downtime during primary hardware or network interruptions.
Rack Allocation and Wiring Interface
The module occupies 2 chassis slots in the control system enclosure, measuring 7.0 cm x 14.6 cm x 13.3 cm and weighing approximately 0.41 kg (0.9 lbs). Field wiring connections utilize a 36-pin TC-TBCH terminal connector, which supports wire gauges ranging from 16 to 22 AWG (0.64 mm to 1.30 mm).
Electrical Power and Circuit Coating
Operating with low power consumption, the TC-PRR021 draws 90 mA at 24 VDC. Depending on the model variant prefix, the unit provides standard component assembly (TC prefix) or conformal coating (TK prefix) to protect internal circuitry against environmental contaminants such as airborne moisture and industrial dust.
