For those installations that support a fieldbus solution such as Modbus RTU or BACnet MS/TP, Contemporary Controls provides solutions for expanding the number of I/O points in the field. Cost-effective Cube I/O modules are available with analog and digital inputs and outputs in varying combinations.
Cube I/O modules are available with varying configurations of analog and digital inputs and outputs. Digital input modules can be configured to support either "wet or dry" contacts up to 10 points. There are also analog input modules to measure voltage and resistance, analog output modules that output voltage, relay output modules and mixed digital input/output modules. All modules operate from a 24 VAC/VDC supply.
Configurable I/O modules provide universal inputs that support temperature, analog, resistance and binary in a single module. For applications not requiring universal inputs there are modules with discrete inputs that support contact closure and retentive pulse counting at 100Hz. Additional modules supply a mix of universal inputs and/or discrete with relay outputs and analog outputs. A single module supports BACnet MS/TP or Modbus RTU/ASCII with a simple dip switch selection.
