TDO16AIN
Termination Card Introduced Power
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.
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
•
Overvoltage protection
•
Dummy loads for unused digital output channels—to prevent spurious operation of
latent fault detection circuits in the associated digital output module. (Dummy loads
are only to be connected to outputs which are not used).
This document is intended to provide a general understanding of the function of the TDO16AIN,
sufficient to enable basic maintenance operations to be effected in the field.

Page 4: Technical Description
TECHNICAL DESCRIPTION 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 DIN41612 connector attached and mounted on rail EN 50022 type NS 35/5. - Page 5 Triguard SC300E TDO16AIN 16-Channel D/O Termination Card 24Vdc Figure 2-2 Leading dimensions and mounting schematic TDO16AIN October 2005 – Issue 6...

Page 7: Theory Of Operation
Triguard SC300E TDO16AIN 16-Channel D/O Termination Card 24Vdc THEORY OF OPERATION Figure 2-4 shows a circuit diagram of a typical digital output channel. Power supplies for the termination cards are normally provided by a Power Distribution Panel PDD24. Power for the digital output channels is distributed as shown in Figure 2-3 . Soldered links LK1 to LK4 are normally present, and in low load applications, external power can be connected to any one of the four inputs FS1 to FS4. - Page 8 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. TDO16AIN October 2005 – Issue 6...
- Page 9 Triguard SC300E TDO16AIN 16-Channel D/O Termination Card 24Vdc SUPPLEMENTARY INFORMATION Dummy loads Dummy loads are only to be connected to outputs that are not used. Do not connect a dummy load in parallel with a real output. Digital output channel connections Table 2-2 lists the digital output channel wiring connections and associated fuses for connector J1 and the screw terminals.
- Page 10 Triguard SC300E SERVICING SCOPE The TDO16AIN contains all-passive circuitry that is extremely robust. Servicing operations will therefore not normally extend beyond the replacement of blown fuses. CAUTION Before replacing a blown fuse, ascertain the cause of failure, and take the appropriate remedial action.
