Multi-protocol module with a mix of heterogeneous I/O: the ultimate controller extension

Powerful I/O module that functions as remote I/O on a serial port with open protocols, BACnet MS/TP, and Modbus RTU/ASCII. The open protocol standard offers the versatility of installing the modules in both new and existing structures, whether for system expansion or retrofitting. A mix of the most common input and output types are combined in a space-saving design, allowing the module to be a versatile controller extension, whether in a small or large structure.

5 Universal Inputs

Support for over 20 types of temperature sensors and voltage, resistance, current, and dry contact measurements on each universal input.

5 Digital Inputs

Dry contact inputs - designed for monitoring. The fast 100 Hz pulse counter with override function saves real-time values in EEPROM memory.

4 digital outputs

Digital outputs equipped with 3 A normally open relays allow direct control without additional relays.

4 analog outputs

0-10 V DC control with 10 mA accuracy, PWM mode, and a maximum load of up to 20 mA to power external relays make the output suitable for a variety of scenarios.

Simplified configuration and commissioning process

The module allows for seamless configuration via BACnet, Modbus, or a dedicated free software package. Powered by a USB port, it facilitates local testing and a simple upgrade process, and the high-end RS485 transceiver allows up to 128 devices to communicate reliably with the client on a single bus.
