RESI-8RTD2-SIO 8 RTD Input Module MODBUS RTU (2-wire only)

Our IO modules are designed for any application in the building automation, industrial automation, and infrastructure sectors. With a size of 4/8 or 12MU, depending on the total quantity of embedded IOs, these IO modules fit into any electrical cabinet. We only offer IO modules suitable for the 45mm cutout of a standard electrical cabinet.

By default, we provide two versions of each IO module: One with an integrated RS485 interface with MODBUS/RTU Slave protocol and one with an Ethernet interface and MODBUS/TCP protocol. All IO modules also support a simple ASCII protocol to use the IOs with a media control system or an IoT controller using Node-RED, NodeJs or Python. Ethernet versions support, in addition to the MODBUS/TCP Server protocol, also the MODBUS/RTU protocol via Ethernet. All our modules have a wide power supply range from 12-48 Vdc.

## Functionality

- IO module with 8 inputs for RTD sensors.
- Various RTD sensors can be used with the module.
- 2-wire sensor connection.
- Each channel can be configured for a different type of RTD sensor.
- The RTD sensor input group is galvanically isolated from the rest of the module.
