Core Features & Customer Value

Dual Redundant Configuration: The T9802’s dual configuration supports two digital input modules, providing redundancy for critical applications. For control system engineers, this redundancy ensures continuous operation even if one input module fails, maintaining process monitoring capabilities and preventing unplanned shutdowns. The dual arrangement allows for hot-swap replacement of individual modules while the system remains operational, reducing maintenance downtime and improving overall system availability.

High Isolation Protection: The termination assembly provides 1.5kV DC isolation between input channels and the control system, protecting against ground loops, electrical noise, and voltage transients. This high level of isolation is particularly valuable in industrial environments with multiple power sources and electrically noisy equipment. For maintenance personnel, the isolation protection minimizes the risk of damage to the control system from field wiring faults, reducing repair costs and improving system reliability.

Comprehensive Field Protection: Each input channel is protected by a 50mA fuse, providing overcurrent protection for field devices and wiring. The fuses are replaceable, allowing for quick restoration of service after a fault condition. The termination assembly also features input measurement with 13-bit resolution (5mV), ensuring accurate detection of input signals even in the presence of electrical noise. For plant operators, this protection scheme reduces the risk of damage to field devices and control system components, lowering maintenance costs and improving system uptime.

Typical Applications

The ICS Triplex T9802 is predominantly used in safety instrumented systems and emergency shutdown systems within hydrocarbon processing facilities. In offshore production platforms, this termination assembly typically interfaces with emergency shutdown pushbuttons, fire and gas detection system inputs, and process monitoring devices. The dual redundant configuration ensures that critical safety functions remain operational even if one input module fails, meeting the high availability requirements of offshore installations.

In refinery applications, the T9802 is commonly deployed in fire and gas detection systems, where it provides the termination interface for gas detector inputs, flame detector status signals, and smoke detector inputs. The assembly’s high isolation and field protection make it suitable for the electrically noisy environments typical of petrochemical facilities. The 50mA fuses provide adequate protection for field devices while allowing sufficient current for reliable input detection.

The termination assembly also finds application in power generation plants, particularly in turbine protection systems and boiler control systems. In these applications, the T9802 interfaces with limit switches, pressure switches, and temperature switches that monitor critical process parameters. The wide operating temperature range allows deployment in unmanned remote locations with varying environmental conditions, while the DIN rail mounting simplifies installation and maintenance in control panel enclosures.
