Extension Modules 1AO/4DO
Relay modules, transforming analog output voltage of controller (AO) for the corresponding sequences of four relay states outputs (DO).
4-bit Analog To Digital Converter PAC4

PAC4 is an enhanced version of the PAC14, changing analog signal (0 - 10V) from the controller into 16 discrete volt-free states. It has 4 electromechanical relays with normally open contacts. PAC4 diagram

PAC4T has 4 MOSFET solid state relays.
