4TO (BACnet MSTP / Modbus RS485)
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 Triac Outputs Silent control of AC current with four solid-state outputs with PWM mode and up to 0.5 A load. Manual Override Switches Each output can be manually overridden using a dedicated hand operating switch. 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.
