Overview
The 900B16-0001 is a 16-channel analog output module designed for Honeywell’s ControlEdge
HC900 Process Automation System.
900B16-0001 delivers configurable 0–21.0 mA current outputs.
900B16-0001 is optimized for high-density industrial process control applications requiring reliable
signal transmission to actuators, valves, and other field devices.
900B16-0001 supports dual power sources, group isolation, and advanced diagnostics.
900B16-0001 ensures stable operation in harsh industrial environments and critical control scenarios.
Core Functionality
●16 Configurable Output Channels: Offers 16 analog current outputs (0–21.0 mA), scalable to any
user-defined span per channel for flexible integration with diverse field devices.
●Group Isolation Design: Outputs are isolated in 4 groups of 4 (Channels 1–4, 5–8, 9–12, 13–16) with
500 V DC group-to-group isolation, and 500 V DC isolation from controller logic to prevent cross-
channel interference.
●Dual Power Options: Selectable power supply via DIP switch—internal 24 V DC from the rack
backplane or external 18–36 V DC loop power (default: external power).
●Advanced Diagnostics: Monitors factory calibration, field calibration, and configuration integrity;
provides output current verification feedback to the controller for real-time status tracking.
●Failsafe Capability: Supports user-specified failsafe values to ensure predictable output states if
communication with the controller is interrupted.
●Synchronous Updates: Outputs are updated in sync with the controller’s execution cycle,
eliminating data latency for time-critical control processes.
●Rate of Change Limiting: User-configurable rate limits for each output to prevent abrupt signal
fluctuations, protecting sensitive field equipment.
Compatibility & Installation Notes
●System Compatibility: Exclusively designed for Honeywell ControlEdge HC900 controllers,
compatible with all HC900 rack configurations (4-slot, 8-slot, 12-slot, including redundant power
racks).
●Rack Capacity: Maximum 2 modules per rack when using internal 24 V DC backplane power.
●Terminal Block & RTP: Requires 36-position Euro-style terminal block (900TCK-0001); compatible
with Remote Terminal Panel (RTP) 900RTS-0001 for simplified wiring and maintenance.
●Cable Compatibility: Uses pre-wired RTP cables (900RTC series) in lengths of 1.0, 2.5, or 5.0 meters.
●Installation Restriction: Cannot be installed adjacent to another 900B16 module; only one 900B16
module is allowed per adjacent slot.
