iSMA-B-MIX38

Multiprotocol Module with a MIX of I/O’s – the Ultimate Controller Extension
The most versatile I/O module with 38 inputs and outputs, offering the most cost-effective price per point ratio. 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.
Reliability of operation is confirmed by UL testing, certified by Underwriters Laboratories.
