Why Choose the IMO IOS/M08ICX-D1 RTD Input Remote I/O Module?
The IOS/M08ICX-D1 offers eight precision RTD inputs on an RS-485 Modbus RTU network. Supporting Pt100 sensors in 2-, 3-, or 4-wire configurations, it delivers 0.1 °C resolution over –200 °C to +850 °C. Ideal for distributed temperature monitoring, it reduces wiring runs and offloads analog acquisition to remote panels powered by 20.4–28.8 V DC.
Key Features of the IOS/M08ICX-D1 Module
- 8 RTD Inputs: 2-, 3-, or 4-wire Pt100 support, 0.1 °C resolution.
- Modbus RTU Interface: RS-485 half-duplex with up to 32 nodes.
- Voltage: 20.4–28.8 V DC nominal power.
- Form Factor: 176.6 × 50 × 39 mm; DIN-rail mountable IP20 enclosure.
- Diagnostics: LEDs for power, comms, and per-channel fault.
- Operating Range: 0 °C to +50 °C; –25 °C to +70 °C storage.
How to Install the IOS/M08ICX-D1 Module
Snap onto a 35 mm DIN rail, wire panel power (20.4–28.8 V DC), connect Pt100 sensors to the input terminals, daisy-chain the RS-485 bus, set address/baud via DIP switches, and verify via LEDs.
IMO IOS/M08ICX-D1 – 8 Pt100 RTD Inputs via Modbus RTU
The IOS/M08ICX-D1 expands Modbus RTU networks with high-accuracy RTD sensing. Its built-in excitation and cold-junction compensation ensure stable readings. Robust surge protection and opto-isolation guard against noise and harsh industrial conditions.
