Industrial 20mA Current Loop to RS-232 Converter
Greater RS-232 distances and signal
protection
Features
• 10-30 VDC operation
• 2-way isolation, 2000V input-output
• Fixed terminal blocks
• Wide temperature ranges (-40 to 80˚C)
Current loop signals can often transmit over lines that serial
signals can’t traverse reliably, due to distance, marginal
conductors or electrical noise. Model 232CLDR interfaces
RS-232 to the most common current loop ports, 20mA with
open circuit voltages.
Contact B&B Electronics technical support for information on
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. Requires
external power supply that is not included.

Isolated RS-485 PLC Converters
Protect your Allen-Bradley ® SLC PLC ® from
damaging surges, spikes and ground loops
Features
• 2000 VDC optical isolation
• DIN rail mount with panel
mount option
• Compare to 1747-AIC
• Baud rate up to 19.2 kbps
• DIN rail mount with panel mount option
• UL recognized
• No power supply required
• Compact design, complete with cables
• Protect your PLC from transients on
your RS-485 network
This PLC optical isolation link connects easily between your
Allen-Bradley model SLC 500, 5/01, 5/02 or 5/03 and your
RS-485 network. It protects your PLC against ground loops,
spikes and surges from data and control lines. Compare this
unit to 1747-AIC.
The included 2 foot (61 cm) cable connects the RJ45 socket of
the isolator and your PLC. Terminal blocks provide the RS-485
link to the network. No power is required as the module draws
power from the PLC. An external power supply (not included)
may also be used.
RS-232 to RS-485 PLC Converter
Quick, easy connection from your PC to Allen-
Bradley ® PLC ® programmable logic controllers
Features
• Monitor and control A-B SLC 500, 5/01, 5/02 and 5/03 PLCs from your laptop or PC
• Optical isolation protects against ground loops and surges
• LEDs monitor communication traffic
• Compact in-line case complete with cables
• No power supply required
Connect your laptop or PC directly to Allen-Bradley SLC 500,
5/01, 5/02 and 5/03 programmable logic controllers. This is an
RS-232 to data highway / DH-485 converter, comparable to the
converter provided by Allen-Bradley for this application. 2000
V optical isolation protects against ground loops and surges. A
