64 channels Unbussed Power Relay Controller USB & RS-232 Controlled

The IA-3171-U2i-P is an Industrial Grade USB and RS-232 Relay Controller, CE and FCC approved, ROHS compliant. This reliable module is designed to operate on the Factory Floor in a harsh, noisy, EMI/RFI Environment. The USB port is Optically Isolated, to ensure the Host Computer Isolation from the Factory Floor.

The IA-3171-U2i-P includes 64 High Voltage Relays that are structured as 8 Groups of 8 Relays each, without any connection between the relays. For a bussed relay solution kindly refer to the IA-3172-U2i relay controller. Each relay is protected by a Voltage Suppressor device, keeping low RFI noise and prolongs relays life. A built-in buffered Local expansion facility enables the operation of thousands of relays via a single communication port, supported by Global and Synchronizing commands.

The controller default BR is 19200, while supporting up to BR 115200 on multi-drop operation.
