GC-4622 user manual
1. Function Introduction
1.1 Functional Overview
GC-4622 (2-channel analog output module, -10V~+10V) can be used to output
signals in the range of +10V~-10V. The terminal module can provide electrical
isolation signals with a resolution of 16 bits for the processing layer. The GC-
4622 module has two two-wire output terminals, which are particularly suitable
for installation in a control cabinet to save space. The GC-4622 module has a
common ground potential, and the power contacts are connected together. The
reference ground at the output is the 0V power contact.
