Isolated Inputs & Relay Output PC Enabled Module Intelligent Appliance Central Relay Control Description The IA-3302 Relay & Isolated Inputs Module is a scalable, flexible and low cost solution for PC based control. It can be controlled remotely by any standard PC, using the simple RS-232 protocol. The module includes 2 opto-isolated digital inputs to protect your PC from external equipment and 2 relay outputs for connecting up to 115VAC/30VDC. It supports both AC and DC as power sources. The module can be mounted on a din-rail for easy installation. 4 indicator LEDs are located at top of the IA-3302, indicating the inputs and relay status. Applications Gate control Central control systems Factory floor control Intelligent alarm systems Laboratory instrumentation control Data acquisition and control applications.
