Analog input module Z-4RTD2-SI

Modbus RTURS485micro USB

The Z-4RTD2-SI is a 24-bit resolution converter for platinum or nickel resistance thermometers (Pt100, Pt500, PT1000, Ni100, Ni120, Ni1000, Cu50, Cu 100) with four independent measuring channels. The module features 3-way isolation up to 1.5 kVac (Power supply // Input channels // RS485 serial communication). Wiring the power supply and serial bus via the Z-PC-DINAL2-17.5 accessory (or Z-PC-DIN2-17.5 for existing BUS extensions) ensures a quick and easy DIN-rail setup. Via the micro USB port on the front, the device can be configured via EASY Setup PC software. Configuration parameters can also be set via DIP-switch.
