Universal transmitter AR593, RTD/TC/mA/V input, 0/4-20mA and 0/2-10V output, isolated, DIN rail

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.
