Input Connections (J4, J5, J6)
Input connections on Terminals J4, J5 and J6 are all contact closure inputs. The inputs can be individually
configured (via DIL switch SW2) to be normally open or normally closed. Figures 6 and 7 show how to
make input connections. All input connections are power limited and supervised.
The maximum cable length between the input device and the SRM must not exceed 3 metres.
Note: The triggering resistor used can be a 470Ω resistor (shown) or a 680Ω resistor.
