INTRODUCTION
PURPOSE
The TDO16AIN 16-channel digital output termination card acts as an interface between the
digital output circuits of an SC300E chassis and the field devices which they control.
October 2005
It provides:
• Screw terminals 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
•
• Dummy loads for unused digital output channels—to prevent spurious operation of

PHYSICAL
The TDO16AIN comprises a PCB assembly mounted in a moulded carrier that can be snapped
onto all commercially available styles of DIN EN 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 TDO16AIN with the DIN4
type NS 35/5.
