Profile: Analog Digital Technology LLC is a manufacturer of signal conditioning modules. Our products include temperature transmitters (both RTD and T/C), isolators, analog computing modules, integrators, indicators, alarms and loop power supplies. The transmitter line comes in two, three or four-wire models. Model SCX 102 loop powered isolator/repeater provides a solution for ground loops and problems encountered in connecting together recorders, process control systems and computers. It accepts a 4-20 mA signal, and provides an isolated 4-20 mA output. Operating power is derived from the input signal, so no external power source is required. DIN mounting is supplied as standard. Model ACA 140 AC current/voltage single alarm accepts a standard AC current/voltage input signal, and provides one (1) DPDT relay contact output setpoint rated at 10 amps, 30 VDC or 250 VAC resistive.
