Honeywell TK-ORC161 97180373 Chassis Series-A Isolated Discrete Relay Module

The Honeywell TK-ORC161 is a conformal-coated, 16-point isolated discrete relay output module designed for the Experion Chassis Series-A (CIOM-A) I/O platform. The device operates within Experion LS systems in conjunction with C200E/C200 control processors over the I/O ControlNet network. Featuring 16 individually isolated Normally Open (N.O.) relay contacts, the module provides high-density discrete output switching capabilities for a wide variety of field devices, loads, and industrial control applications.

Features

• Conformal Coating: Includes factory-applied conformal coating (TK series) for enhanced corrosion protection in harsh industrial environments (ANSI/ISA-S71.04-1985 Moderate G2 or Harsh G3 classification).
• High-Density Channel Count: Equipped with 16 N.O. relay contact output channels in a single-wide chassis slot form factor.
• Individual Galvanic Isolation: Provides point-to-point channel isolation (16 N.O. contacts individually isolated) to ensure electrical independence and signal integrity across field circuits.
• Versatile Switching Capacities: Handles switching voltages from 10 to 265 VAC (47-63 Hz) and 5 to 150 VDC.
• Configurable Channel States: Features user-configurable Fault States and Program Mode states per point (Hold Last State, ON, or OFF; default is OFF).
• Hot-Swappable: Supports Removal and Insertion Under Power (RIUP) in non-hazardous/ordinary locations.

Applications

• Motor starter control circuits
• Solenoid valve actuation
• Annunciator panels and alarm indication outputs
• High-voltage interlock and isolation switching
• Interfacing field actuators with C200E/C200 Control Processors in process control systems

Installation Guidelines

• Chassis Slot Placement: The module occupies a single-wide slot within any position of an Experion Series-A chassis.
• Terminal Wiring: Connect field wiring directly using the TC-TBCH 36-pin terminal block or via pre-wired cable assembly connected to a Remote Terminal Panel (RTP).
• Fusing Protection: Outputs are not internally fused; use a fused RTP (e.g., Allen-Bradley 1492 interface system) to protect module output circuits against overcurrent conditions.
• Removal and Insertion Under Power (RIUP): Permitted in ordinary, non-hazardous locations. RIUP is strictly NOT PERMITTED when installed in Class I, Division 2 hazardous locations.
• Enclosure Requirements: Maintain compliance with ambient environment criteria (0 to 60 degC operative temperature limits) inside an industrial enclosure.
