Multiprotocol I/O module with 8 digital inputs.

Powerful I/O module that works as a remote I/O over a serial port with open protocols, BACnet MS/TP and Modbus RTU/ASCII. The module is equipped with 8 digital inputs, which makes it a perfect monitoring device. A compact size and ease of installation allow the module to be fitted even into limited space installations.

8 Digital Inputs
Dry contact inputs were made for monitoring. 100 Hz fast pulse counter with override function saves the real-time values to the EEPROM memory.

Simplified Configuration and Commissioning Process
The module allows for seamless configuration over BACnet, Modbus, or dedicated free of charge tool. The ability to be powered from a USB port facilitates local testing and a straightforward updating process, and the high-end RS485 transceiver allows up to 128 devices to communicate reliably with the client on a single bus.
