Current Loop to

Serial Converter

Model 232CL9R

www.advantech-bb.com

PRODUCT FEATURES

•

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)

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.

ACCESSORIES

Current Loop Explained

SM16-12-V-ST - Power Supply, 12VDC 500mA, stripped and tinned leads, Level VI

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.

SERIAL TECHNOLOGY

Data Rate

RS-232

Current loop converters from B+B SmartWorx interface RS-232 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 SmartWorx’ 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.
