Multiprotocol Module with a MIX of I/O's - the Ultimate Controller Extension

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. Open protocols standard offers the versatility of installing the modules in both new and existing facilities, whether it is a system expansion or a retrofit. The most popular types of inputs and outputs are MIXed in a space-saving design and allow the module to be a versatile controller extension, whether in a small or large facility.

8 Universal Inputs

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

12 Digital Inputs

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

12 Digital Outputs

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

6 Analog Outputs

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

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.

Quality and Reliability Confirmed by Certificates

iSMA CONTROLLI is a long-standing member of the BACnet community. The experience in developing high quality products and the BTL (BACnet Test Laboratory) certification confirm the excellent performance of communication using the BACnet protocol.
