This MELSEC iQ-R Series input unit from MITSUBISHI ELECTRIC reads digital signals from sensors, switches and push buttons. Connector or terminal block versions offer different point counts and input types. High-speed input versions support fast signal detection. Sink and source types are available, so the unit can be matched to the sensor wiring standard used in the machine.
