Relay Functionality
The relay is operated by setting output bit 0. If the supply voltage is removed, the relay
will not change state. When the Relay Output Module is powered up, the relay will be
in the same state as it was prior to the module being switched off but the module will
respond to output bit 0 four seconds after power has been applied. If the module has
not been interrogated, a relay reset will automatically be applied.
Address Setting
Segments 1-7 of the DIL Swtich are used to select the address of the module. Each of
the seven segments must be set to ‘0’ (ON) or ‘1’ (OFF) using a small screwdriver or
similar tool. A complete list of address settings is shown below.
