REX610 Technical Manual

The parameter Input # invert is used to invert a binary input.

Table 1. Binary input states
Control voltage Input # invert State of binary input
No 0 FALSE (0)
Yes 0 TRUE (1)
No 1 TRUE (1)
Yes 1 FALSE (0)

When a binary input is inverted, the state of the input is TRUE (1) when no control voltage is applied to its terminals. Accordingly, the input state is FALSE (0) when a control voltage is applied to the terminals of the binary input.
