September 20, 2012 - Online-Devices announced a new Relay Multiplexer Board with 32 Differential Channels or 16 Quad Channels, with a contact rating of 2 Amp @ 30VDC and 1Amp @ 115VAC. This new board, IA-3133-U2i, is made by Intelligent-Appliance, an innovative manufacturer, specializing in Data Acquisition and Control products for the Industrial, Building Control and Agriculture fields. Controlling the IA-3133-U2i is a very simple task. The onboard firmware makes sure only one single channel is operating at any given time, while ensuring “Make-before-Break” functionality, for multi-source secure operation. The IA-3133-U2i can be controlled by either USB or RS-232 port, and it includes a simple, transparent Daisy-Chain structure for an easy operation of up to 256 units.
The onboard USB port is of Virtual COM port nature, and it provides a Galvanic isolation between the PC to the relay multiplexer, eliminating any possible ground loop operation problems.
