Description
1. At-A-Glance Executive Brief
- Model: T9851
- Brand: ICS Triplex (Rockwell Automation)
- Part Type: Digital Output Termination Assembly (TA) / 8-Channel Simplex Configuration
- Lifecycle Status: Active Safety Component / Secondary Supply Chain Inventory
- Weight: 340 g (12 oz.)
- System Compatibility: AADvance Safety Instrumented System Architecture (Supports T9451 Digital Output Module)
2. Technical Introduction
Safety instrumented output loops driving critical elements like emergency shutdown solenoids and trip valves require dependable power distribution and signal routing. The ICS Triplex T9851 functions as an 8-channel simplex digital output termination assembly, engineered to connect field wiring safely to corresponding AADvance output cards. Deploying this termination module requires verifying field supply voltage parameters and ensuring proper fuse ratings to protect output loops against overcurrent conditions.
- Best Suited For:
- Direct replacement of failed simplex output termination assemblies in legacy AADvance safety racks.
- Managing 24V DC field power distribution for standard safety output loops.
- Maintaining compliant signal paths during routine plant expansion or maintenance windows.

- Operating Voltage Range: 24V DC nominal (18V DC to 32V DC range)
- Field Supply Fuses: Replaceable 10A fuses protecting field power input
- Continuous Output Current: 1A continuous per channel
- Environmental Tolerances: Please refer to the OEM datasheet for complete environmental tolerances.
4. Field Engineer’s Tech Notes
- Field Power Fuse Inspection: The T9851 incorporates replaceable 10A fuses to protect field power inputs. If an entire group of output channels loses field power or registers a supply fault, inspect these onboard fuses using a non-conductive tool before swapping out the wider assembly.
- Conductor Stripping and Torque Limits: When terminating field conductors into the removable terminal blocks, strip wire insulation precisely to 6 mm (1/4 in.). Adhere to proper screw tightening torques to prevent high-resistance joints or loose connections under continuous industrial vibration.
5. Adaptive QA & Testing Protocol
Each T9851 termination assembly undergoes rigorous bench validation prior to warehouse release. Technicians mount the module to a live test fixture to verify trace continuity across all 8 channels, check isolation boundaries, and validate fuse continuity under simulated load currents. Removable terminal block mechanics are checked for structural integrity. Detailed test verification reports are available upon request prior to shipment.
6. Buyer’s FAQ
- What inventory conditions are available for this module?
We supply this termination assembly in factory New Surplus (NSFP) and fully tested refurbished conditions, explicitly documented on all commercial paperwork.
- What warranty coverage applies to this safety hardware?
Every unit is backed by a standard 12-month operational warranty covering component integrity and functional performance from the invoice date.
- How are static-sensitive safety assemblies packaged for transit?
Units are sealed in heavy-duty moisture-barrier anti-static packaging and secured within custom structural foam containers to eliminate ESD and physical impact hazards during transport.
