Digital Input Configuration
Digital Input Field wiring for all digital input variants are made through the iBox's terminal
Field blocks, separable in pairs.
Connections
Digital Input The digital input is wetted (or turned ON) by closing a contact across the two input
Wetting termination points. The voltage that is switched at the input terminals is supplied by
Selection an external source. The external power source is connected to terminal block TB-10,
positions 1 and 2, as shown below.
!
All eight digital inputs are bipolar. Use care when connecting multiple external
power sources, since the digital inputs have common returns.
Wiring This diagram illustrates the DC input connections, from Input #1 (TB2) through
Diagram: Input #8 (TB9). TB10 accepts DC voltages of either polarity. The input voltage level
Dry Contact to TB10 is determined by the purchased option.
