Description: Black Box HS RS-232<->Current Loop Interface Converter - Transceiver - RS-232 - serial - 25 pin D-Sub (DB-25) / terminal block
Mfr Part #: CL1090A-F-US
The converters can be configured for active or passive Current Loop. In active mode, an async RS-232 device can communicate with a passive 20-mA Current Loop device. In passive mode, an async RS-232 device can communicate with an active 20-mA Current Loop device.
These compact solutions are configured as RS-232 (DCE), but they can be modified for DTE use with an asynchronous modem eliminator (ME212).
Each converter has a transmit (T+ and T-) and a receive (R+ and R-) loop. Optical isolators in both the transmit and receive loops keep out electrical interference and eliminate ground loops.
- Bidirectional conversion of RS-232 to 20-mA Current Loop
- Active or passive operation
- Optical isolation
- Compact size
