AR654/S1/P/P/P/P/IP65 is an APAR four-channel universal controller with built-in data recording, in a 96x96 mm panel case with a 320x240 colour touch screen. Each of the four outputs runs its own ON-OFF, PID with auto-tuning or 12-step program, on any input or on the difference, sum or average of inputs.

• Inputs: 4 universal - Pt100/Pt500/Pt1000/Ni100, thermocouple J/K/S/B/R/T/E/N, 0/4-20 mA, 0-10 V, 0-60 mV, 0-850 Ω, not galvanically isolated
• Outputs: 4 relays SPST 5 A/250 VAC
• Recording: 4 GB internal memory or USB flash drive, text file readable in Excel
• Communication: Ethernet (Modbus TCP, web server, e-mail alarms), RS485 Modbus RTU, USB
• Supply: 230 VAC (85-260 VAC), 24 VDC output for transmitters
• Housing: 96x96x79 mm, cut-out 92x89 mm, IP65 front (USB at the rear only), IP20 terminals

Current values, output states and trends are visible in a web browser on the LAN, and the free ARsoft-LOG and ARsoft-CFG (Windows) read the archives and set parameters. Analogue outputs and binary inputs need the optional W module, which this version does not have.

AR653.B/P/P/P/WA is an APAR two-channel universal controller in a 96x48 mm panel case. Each input accepts an RTD, thermocouple, mA, V, mV or resistance signal, and the controller can regulate on either input or on the difference, sum or average of the two - for example a supply and return temperature difference.

• Inputs: 2 universal - Pt100/Pt500/Pt1000/Ni100, thermocouple J/K/S/B/R/T/E/N, 0/4-20 mA, 0-10 V, 0-60 mV, 0-2500 Ω
• Outputs: output 1 relay SPDT (ON-OFF, PID, auto-tuning), outputs 2 and 3 relay SPST-NO, 8 A/250 VAC
• Analogue output: 0/4-20 mA, for control or retransmission
• Supply: 20-250 VAC / 15-350 VDC, 24 VDC/50 mA output for field transmitters
• Housing: 96x48x79 mm, panel cut-out 92x46 mm
• Environment: IP65 front, IP20 terminals, 0...50 °C

Parameters are set from the front keypad, or from a PC with ARsoft-CFG through the PRG port and an APAR programmer, which also copies a complete parameter set to the next controller. This version has no RS485 interface.

Electromagnetic compatibility: immunity to PN-EN 61000-6-2, emission to PN-EN 61000-6-4.
