Configuration of the input type. Configurations available for different controllers are as follows: SP2 Basic(normally open, normally closed); SP2 BasicInd(normally open,normally closed, temperature, temp 4-20mA, voltage); Compack inputs 1-4(clock, virtual),inputs 5-7(normally open,normally closed, temperature, temp 4-20mA, voltage, clock); SmartpackS inputs 1-4(clock, virtual), inputs 5-8(normally open,normally closed,voltage,temperature,temp 4-20mA), inputs 9-10(normally open,normally closed,voltage); Smartpack R inputs 1-6(normally open,normally closed,diode matrix,clock, voltage),inputs 7-10(clock, virtual).
