The IA-3174-U2i is an Industrial Relay Controller Board that includes 32 DPDT relays with a complete 6 contact support on each of them, featuring a wide range of wiring combinations, including differential and dual differential multiplexing. The board is supported by the rich Series-3000 commands list, with two new additional commands, for a smart single and twin relay operation, with an on board “Break-before-Make” facility. The IA-3174-U2i Relay Controller supports a Daisy-Chain operation. It includes a buffered output port communication method, enabling a simple and a transparent control over a massive amount of boards. The IA-3174-U2i Software Support package includes USB software drivers, open source code samples as well as setup and configuration utilities for fast product implementation.

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.
