description

Convert 20 mA current loop to RS-232

Current loop signals often can transmit over circuits that serial signals can’t traverse reliably, due to distance, marginal conductors and electrical noise. Model 232CLDR interfaces RS-232 to the most common current loop ports, 20mA with open circuit voltages up to 30 V. Contact B&B Technical Support for information on higher loop currents and voltages. Maximum baud rate for current loop converters is 19.2 kbps.

The transmit loop and receive loop each can be operated as active or passive. All connections are made on terminal blocks. A single power supply (not included) between 10 and 30 VDC can power the converter and both current loops.
