ZIO 1244 Remote Input/Output Module
ZIO 1244 Input/Output module is designed to measure the DC and AC values of the Pipe to Soil potential simultaneously.
The Module can transfer the measured data to the SCADA system over either 4-20mA Analog outputs or through RS485 MODBUS.
Wide input voltage range allows module to be powered with 12-50 VDC. Reverse polarity protection assures modules connection safety. ZIO1244 also offers 4 Digital Inputs and 4 Relay Outputs for general purpose usage.
