Flow meter AR715/S1/P/P/WA, pulse counter, PNP/NPN/reed inputs, 2 relays, 0/4-20mA output, 230VAC

AR715/S1/P/P/WA is an APAR panel meter that is set up as a flow meter with totaliser, pulse counter, encoder counter, batch dispenser or frequency meter. Two pulse inputs take NPN or PNP open-collector or contact (reed) signals, and the built-in 24 V supply powers the flow meter or encoder directly.

• Measurement: flow and total, pulse count, speed and position from an incremental encoder, dosing, frequency
• Input frequency: up to 10 kHz for flow and speed, 30 kHz counting with PNP, 100 kHz counting with NPN
• Outputs: 2 relays 8 A/250 VAC, analogue 0/4-20 mA for alarm or retransmission
• Display: 5-digit LED, 14 mm, four programmable colours
• Supply: 230 VAC (85-260 VAC), 24 VDC/50 mA sensor supply
• Housing: 96x48x79 mm, cut-out 92x46 mm, IP65 front, IP20 terminals

Extra inputs S (count enable), R (reset) and B (programmable) let a PLC or push-button start, stop and zero a batch without the keypad. The totaliser holds 10 digits with sign. This version has no RS485; parameters are set from the keypad or through the PRG port with an APAR programmer.
