Description
The IA-3121 is an intelligent 32 Relays (Solid State ones), module, controlled by Dazy-chain RS-232 Communication method, and is a part of the IA Multi system Series. This module has been especially designed for Inductive Loads, and for massive operations cases. Each output includes a protective diode, thus eliminate the user need to implement a protective element on each load. Special care should be taken while connecting the loads to this module, as this module is capable of operating DC loads of up to 30VDC, while it CAN NOT operate AC LOADS! Dazy-chain operation is totally transparent to the user. It has no affect on the cards operation, while enabling the user of adding additional modules to the same COM Port.
