iSMA-B-4U4A-H I/O Module

Multiprotocol I/O Module in a Compact Size 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. A compact size and ease of installation allow the module to be fitted even into limited space installations. 4 Universal Inputs Support for over 20 types of temperature sensors and voltage, resistance, current, and dry contact measurements on each universal input. 4 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 make the output suitable for a variety of scenarios. Manual Override Switches Each analog output can be manually overdriven using a dedicated manual potentiometer. 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.
