1202 Module - Sub994; 1203 Module - Sub991; Figure 18 4/4 1204 I/O Sub994; Figure 19 8/8 1203 I/O Sub991 - Panasonic Brooks FireTracker FT1020G3 Operation Manual

5.6.2 1202 Module – SUB994
1202 or SUB994 comprises four supervised inputs and four latching relay outputs. The
functions and programming of each input or output is identical to 1200 I/O module.
Connection is similar to 1200 module shown in Figure 17 above and the PCB is shown in
Figure 18 below. The supervised input requires 10K end of line resistor.
The relays used in 1204 are also latching relay type i.e. remains in active condition until
normal status is restored). The module doesn't require external 24V supply and powered
from the COM loop.
5.6.3 1203 Module – SUB991
1203 – SUB991 I/O unit is designed to provide 8 x programmable non-supervised inputs
and 8 x programmable relay outputs, no end of line resistor required. The relays are non-
latching relays which requires external 24V
in Figure 17 page 39 but inputs are not supervised. The physical SUB991 board is shown
in Figure 19 below. 1203 requires two consecutive addresses on the COM loop.
Note: Refer to Technical Datasheet TDS053 for full details on programming and
installation.
