The TDI16AIA 16-channel digital input termination card acts as an interface between the digital
signalling
It provides:
• Screw terminal connectors for the field wiring
• Power supply inputs for the field devices
• Fuse protection for the field loops with local and remote indication of fuse failure

PHYSICAL
The TDI16AIA comprises a PCB assembly mounted in a moulded carrier that can be snapped
onto all commercially available styles of DIN mounting rail. Connection to the chassis
backplane is via a multicore cable terminated at either end by a DIN41612 connector. Figure 2
2 shows the TDI16AIA with the DIN41612 connector attached and mounted on rail EN 50022
type NS 35/5.
Figure 2-1 identifies the main components on the PCB.
