Honeywell 10201/2/1 Digital Output Module

Basic Product Identity: 

■Product Type: Fail-safe digital output module.

■Core Purpose: Provides safe and reliable digital output signals in industrial safety control systems, 

with fail-safe performance to ensure outputs can be de-energized in case of component failure or 

system faults.

Product Identification:

■Type Number: 10201/2/1 (suffix code: 11501).

■Software Compatibility: Compatible with FSC software versions ≥ 3.00.

Core Functional Specifications:

■Output Channels: 8 channels, divided into 2 groups of 4 channels each.

■Output Parameters: 24 Vdc output, maximum current 550 mA per channel, supporting loads up to 

13 W.

■Load Compatibility: Suitable for resistive (e.g., lamps) and inductive (e.g., solenoids) loads; each 

output includes a suppression diode for inductive load protection.

■Fail-Safe Features: Each channel group has independent secondary de-energization means, 

enabling watchdog or processor to cut off outputs regardless of application function results.

■Self-test Functions: Tests include output de-energization capability, group secondary de-

energization, inter-channel crosstalk, and suppression diode functionality.

Electrical Specifications:

■Power Requirements: 5 Vdc (25 mA), 24 Vdc internal (25 mA), 24 Vdc external (70 mA without 

output load).

■Output Performance: Solid-state source output, short-circuit proof; voltage drop < 2.0 Vdc at 500 

mA; off current < 0.1 mA.

■Watchdog Input: WDG input current 4 mA per group.

■Load Limits: Maximum lamp load 120 mA (2.9 W), maximum load capacitance 1 µF.

Pin Allocation (Key Pins)

Installation & Usage Notes：

■Power Connection: Must connect both 24 Vdc internal and external power supplies (pins d8, z8, 

d30/z30, d32/z32) to avoid fault detection during self-test.

■Wiring: Connected to field devices or FTA modules via system cables; analog ground and power 

supply lines need proper isolation to avoid interference.

■Replacement: Can be hot-swapped (power on during replacement), but process operation may be 

affected depending on signal function and system configuration; disconnect the horizontal bus 

flatcable before removal.

■Load Calculation: Consider maximum supply voltage when calculating load current; refer to 

derating curves for current adjustment under high supply voltage.

Mechanical & Compatibility:

■Space Requirements: 4 TE (20.32 mm) width, 3 HE (3U) height, suitable for standard 19-inch I/O 

racks.

■Mounting: Installed in FSC system I/O racks; address determined by rack position (no jumpers for 

address setting).

■Compatibility: Works with FTA (Field Termination Assembly) modules; replaceable with same-type 

modules.
