Description
The PM100 0183 Expander allows multiple listeners to be connected to a single talker. The PM100 takes either a single-ended RS-232 or a differential RS-422 input signal. It conditions and buffers the input signal to provide three single-ended RS-232 outputs and one differential RS-422 output. It also provides up to 2kV RMS input-to-output-to- power isolation using optical and transformer technology. Specifications: Isolation 3-way isolation: Input-to-output-to-power ; Hi-pot: 2000 VRMS for 1 minute, 5500 VDC for 1 second, Leakage Current: Less than 50uA @ 2000 VAC / 60Hz; 5500 VDC Power Supply 9 to 24 volts DC @ 30mA (min), 140mA ( max). 400 volts DC reverse polarity protection.
