GC-4642 user manual
1. Function Introduction
1.1 Functional Overview
GC-4642 (2-channel analog output module, 0-20mA) can be used to output
signals in the range of 0-20mA. This terminal module can provide electrical
isolation signals with a resolution of 16 bits for the processing layer. The GC-
4642 module has 2 two-wire output terminals, which are especially suitable for
installation in a control cabinet to save space. The GC-4642 module has a
common ground potential terminal, and the power contacts are connected
together. The reference ground of the output terminal is the 0V power contact.
