Control relays - Import export

• Measurement of DC voltage, DC current, temperature (RTD, TC) and resistance • Programmable remote I/O functionality. Readout of all input variables and internally calculated values via MODBUS. Simultaneously, the outputs and the relay may be controlled via MODBUS. • Free selection as to whether the output variables are dependent on the input variables or whether the outputs are controlled independently of the inputs via MODBUS. • Sensor connection without any external jumpers • 2 inputs (e.g. for sensor redundancy or difference formation) • 2 outputs (U and / or I) • 2 inputs can be linked with each other and allocated to the 2 outputs which enables calculations and sensor monitoring (e.g. prognostic maintenance of sensors) • System capability: Communication via Modbus interface • Freely programmable relay, e.g. for liwith or alarm signalling • AC/DC wide-range power supply unit • Pluggable high-quality screw or spring cage terminal
