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

TECHNICAL DESCRIPTIO
N
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.

Each digital output channel is powered from a common +ve bus. An indicating fuse is fitted in
the digital output signal line to the field device. The ‘fuse failed’ output from each fuse is
connected to a common alarm bus. If any fuse fails, local indication is provided by the

NOTE
Current for alarm indication is taken from the chassis module digital output signal. An alarm
will be signalled only when the fuse has failed and this output is high.
Power distribution panel PDD24 has a Fuse blown alarm indicator with provision for multiple
inputs.
This facility can be wired to provide fuse blown indication for an entire cabinet.
