Allen Bradley 1715-TASIF16 Redundant I/O Termination Assembly

Configured for high-density signal distribution in 1715-IF16 Analog Input systems, the Allen Bradley 1715-TASIF16 (1715-TASIF16 Redundant I/O Termination Assembly) provides direct physical and electrical execution of field-to-module wiring interfaces.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks

The 1715-TASIF16 assembly manages backplane bus communication velocity by providing a dedicated termination point for the 1715-IF16 analog input module. The assembly maintains deterministic signal path integrity, supporting I/O density scaling within the 1715 redundancy architecture. Firmware flash compatibility is intrinsically managed by the host I/O module, ensuring that analog signals are digitized and mapped according to the configured scan rate of the controller. The assembly ensures galvanic integrity of the input loops, preventing common-mode interference from propagating across the backplane bus.

Frequently Asked Questions

Q: Does the 1715-TASIF16 assembly support hot-swapping of the attached 1715-IF16 module?

A: Yes. The termination assembly is designed to allow for the removal and replacement of the I/O module without disconnecting field wiring, provided the system logic is configured for hot-swap operations.

Q: How is redundancy managed by this specific termination assembly?

A: The 1715-TASIF16 is engineered to serve the 1715-IF16 module in a simplex configuration. When utilized within a redundant system chassis, it serves as the physical interface layer for the primary signal paths, supporting the overall redundancy scheme of the 1715 I/O platform.

Field Installation Guidelines

1. Assembly Mounting: Secure the termination assembly onto the system backplane or chassis rail. Ensure the mechanical alignment pins are fully seated to maintain backplane connector alignment.
2. Field Wiring: Terminate field signal wiring according to the loop diagrams. Use shielded twisted-pair cabling and terminate shields at the designated ground bar on the assembly to minimize electromagnetic interference.
3. Module Seating: Insert the 1715-IF16 module into the termination assembly. Apply firm, even pressure to ensure the multi-pin connector is fully mated to the backplane interface.
4. Torque Specifications: Tighten all terminal screws to the specified torque rating to ensure a gas-tight electrical connection and prevent oxidation over the service life of the module.
5. Loop Verification: Prior to applying field power, measure the resistance of each loop to ground to ensure no shorts or ground faults exist in the field wiring.
