The Moxa ioLogik R1241-T is the wide temperature variant of the ioLogik R1241, delivering 4 analogue output channels for serial control applications in more demanding industrial and outdoor environments. It is intended for projects where analogue setpoints need to be transmitted reliably to remote field devices over RS-485 using Modbus RTU, but where installation conditions may involve freezing weather, unheated enclosures or elevated ambient temperatures. For utilities, infrastructure, energy systems and exposed process sites, the R1241-T provides a compact and dependable way to extend analogue control closer to the equipment being managed.
The module supports 0 to 10 VDC, 0 to 20 mA and 4 to 20 mA output ranges, making it suitable for controlling drives, valve actuators, dampers, transmit interfaces and other analogue-input field devices. It provides 12-bit resolution, supports 10 mA maximum voltage output, and offers load capability up to 400 ohms using internal power or 1000 ohms with 24 V external power in current mode. While the standard and wide temperature versions share the same output functions, the R1241-T is the better fit when the environment is the main design challenge. Its accuracy is specified at ±0.1% FSR at 25°C and ±0.3% FSR from -40 to 75°C, helping maintain dependable performance across a broader real-world temperature range.
Like the rest of the R1200 family, the ioLogik R1241-T includes dual RS-485 ports with a built-in repeater, software or USB configuration, remote firmware updating, 12 to 48 VDC power input, and support for DIN rail or wall mounting. These features help simplify installation in remote cabinets, control kiosks and field panels while also making ongoing maintenance more efficient.
The main reason to choose the ioLogik R1241-T over the standard model is its -40 to +85°C operating temperature range, which makes it a better option for exposed industrial sites where reliable analogue output control must continue despite colder winters, hotter enclosures or greater day-to-night thermal
