Digital Input Parameters
Digital Input A.
This is an optional input wired to terminals C and LA. The input is typically from a voltage free contact,
which can be configured to operate a number of functions as determined by parameters in the LA List.
☺
3216 controllers can be fitted with optional EIA232 digital communications. In this case the digital input is not
available.
Note: Terminal C is common to the CT input and is, therefore, not isolated from the CT.
Digital Input B.
This is wired to terminals LB and LC and is available in 3208 and 3204 controllers only.
The parameter lists are identical as shown below:-
