4U-4A (Modbus RTU/ASCII / BACnet MSTP)
Multiprotocol IO/ 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.
