Remote I/O devices optimize automation control systems
Packaged in a rugged nickel- plated brass and PVC body, the hub has IP65, IP67, and IP68 ratings for indoor use only. Analog signals predate automation, but since many sensors still have them as outputs, they need to be converted to Modbus or IO-Link protocols. The Banner Engineering R45C-2K-MQ 2-port converter reads two analog signals as a voltage or a current and outputs them in a Modbus protocol. Analog inputs are made via two M12 female connectors, while the output is via a five-pin M12 male connector. LEDs indicate the input and output status. The R45C-2K-MQ is powered from an 18 to 30 volt DC source with a maximum current draw of 4 amperes (A) at 24 volts. The converter operates over a temperature range of -40 to +70°C and is environmentally rated at IP65, IP67, and IP68 for indoor use only. Data converters can also take digital commands from the master controller and output an analog voltage for devices such as pneumatic actuators, solenoids, or motor starters. The converter can be located near the controlled device, minimizing analog signal losses and electromagnetic interference. The Banner Engineering R45C- K-UQ converter (Figure 5) allows automation designers to output an
