KL3222 BECKHOFF Bus Terminal 2-channel analog input PLC Module

KL3222 BUS TERMINAL, BECKHOFF PLC Module is Manufactured by BECKHOFF, 2-CHANNEL, ANALOG INPUT, 500 V, 60 MA, TEMPERATURE, PT100 (RTD), FOR 4-WIRE CONNECTION, HIGH-PRECISION, IP20.

The KL3222 analog input terminal allows resistance sensors to be connected directly. Linearization over the full temperature range is realized with the aid of a microprocessor. The temperature range can be selected freely. The run LEDs give an indication of the data exchange with the Bus Coupler. The error LEDs indicate sensor faults (e.g. a broken wire).
