RS232 TO CURRENT LOOP CONVERTER S

Control Current Loop devices from your PC. 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.
