Current Loop to Serial Converter
232CL9R
Model 232CL9R is a port-powered RS-232 to current loop converter. No
external power required for passive loop installations, but a power supply is
required to generate an active loop.
• Optically isolated digital current loop to serial conversion
• Baud rates up to 19.2 kbps
• Transmit (T+ and T-) loop and Receive (R- and R-) loop
• Each current loop may be operated active or passive
• Designed for 20mA digital current loop (other values available)

Current loop explained
Current loop devices use Current On or Current Off to transmit binary digits.
Current loop signals can often transmit over circuits that serial signals can’t
traverse reliably, due to distance, marginal conductors and electrical noise.
Current loop converters from B&B Electronics interface RS-232 or RS-
422/485 to the most common current loop ports – 20mA with open circuit
voltages up to 30 V – at a maximum baud rate of 19.2 kbps. High speed
optical isolators couple and isolate Transmit and Receive data. All B&B
Electronics’ current loop converters have a transmit (T+ and T-) loop and a
Receive (R+ and R-) loop. Each loop may be operated as an active or passive
loop. When the converter needs to provide the loop current, a 12 VDC power
supply is required for the current loop side.
Contact B&B Electronics for information on modifications for higher loop
currents and voltages.
