AR593 is an APAR programmable transmitter and signal isolator for 35 mm DIN rail. It converts an RTD, thermocouple, mA, V, mV or resistance input into a current and a voltage output at the same time, with 1.5 kV isolation between input, output and supply.

• Input: Pt100/Pt500/Pt1000/Ni100 2- or 3-wire, thermocouple J/K/S/B/R/T/E/N, 0/4-20 mA, 0-10 V, 0-60 mV, 0-2500 Ω
• Outputs: 0/4-20 mA active (load ≤ 500 Ω) and 0/2-10 V, also inverted
• Accuracy: 0.1 % of range, thermocouples additionally <2 °C
• Supply: 24 VAC/DC (18-50 VDC, 13-35 VAC), <850 mW
• Response time: 360 ms, adjustable 0.24...1.6 s
• Housing: 35 mm DIN rail, IP20, 0...65 °C

Factory setting is Pt100, 0...500 °C, 4-20 mA and 0-10 V; another input or range is set with an APAR programmer, or by APAR when specified with the order (e.g. AR593 / J / 0..20 mA / 100..600 °C). The current output is active and cannot be used in a loop-powered 2-wire circuit. A red LED shows range exceedance, sensor fault or alarm.
