Honeywell TK-PRR021 51309288-475 is a double-wide redundancy module designed for the Experion Chassis Series-A (CIOM-A) platform to support C200 control processor redundancy configurations. Operating within Experion LS and Experion PKS process control architectures, the TK-PRR021 facilitates synchronized, fault-tolerant operation between dual controller chassis.
Equipped with factory-applied conformal coating, Honeywell TK-PRR021 provides corrosion protection in environments rated Moderate (G2) or Harsh (G3) per ANSI/ISA-S71.04-1985 standards. The module occupies two chassis slot positions and draws power directly from internal backplane voltage rails to maintain continuous high availability in industrial process applications.
