Description

The Moxa ioLogik R1240 is a serial remote I/O module with 8 differential analog input channels that accept voltage or current signals, built for connecting field sensors to a Modbus RTU network. It offers 16-bit resolution, input ranges of 0 to 10 VDC, 0 to 20 mA and 4 to 20 mA, and dual RS-485 ports, in the standard -10 to 75°C temperature version.

The unit operates as a Modbus RTU server (slave) and can be configured and firmware-updated over USB or RS-485 using the ioSearch utility. A built-in repeater function and multidrop parameter installation simplify larger serial deployments, and the compact plastic housing mounts on a DIN rail or wall, powered from 12 to 48 VDC.

Features

- Dual RS-485 remote I/O with built-in repeater
- Supports multidrop communications parameter installation
- Install communications parameters and upgrade firmware via USB
- Upgrade firmware through an RS-485 connection
- Configure and update devices through the ioSearch utility
- Compact housing with DIN-rail or wall mounting
- Screw-fastened Euroblock terminals for I/O and power wiring

FAQs

Q: What type of signals can the ioLogik R1240 read?
A: It has 8 differential analog input channels that accept voltage or current signals, with ranges of 0 to 10 VDC, 0 to 20 mA and 4 to 20 mA (the 4 to 20 mA range also supports burn-out detection).

Q: Which protocol does it use to communicate?
A: It operates as a Modbus RTU server (slave) over its two RS-485 ports, so it needs a Modbus RTU master such as a PLC, gateway or SCADA system to poll it.

Q: How is the ioLogik R1240 configured and updated?
A: Communications parameters can be installed and firmware upgraded over USB, and firmware can also be upgraded through an RS-485 connection. The ioSearch utility is used to configure and update devices.

Q: What power supply does it require?
A: It runs from a single 12 to 48 VDC input and draws 216 mA at 24 VDC. Power is connected through a screw-fastened Euroblock terminal.

Q: What operating temperature range does this model support?
A: This standard model operates from -10 to 75°C. A separate -T variant is available for wide-temperature environments.

Q: How can it be mounted?
A: The compact plastic housing supports DIN-rail or wall mounting.
