Description

The Moxa ioLogik R1241-T is a wide-temperature RS-485 serial remote I/O unit with 4 analog output channels, built for industrial automation and process control. It supports 0 to 10 VDC, 0 to 20 mA and 4 to 20 mA output ranges at 12-bit resolution, and operates from -40 to 85°C, making it suited to harsh and unheated environments such as outdoor cabinets, pump stations and factory floors.

Two RS-485 ports with Modbus RTU server (slave) support provide wiring and computer redundancy, with a built-in repeater for multidrop networks. Communication parameters and firmware can be installed or upgraded over USB or an RS-485 connection, and configuration is handled through the ioSearch utility. The unit mounts on a DIN rail or a wall and accepts a 12 to 48 VDC power input.
