Hour and pulse counter combinations for flush and surface/DIN-rail mounting, for AC or DC, 48 x 48 mm Here you will find a solid solution for a hour and pulse counter combination. Choose between flush or surface/DIN-rail mounting. The connections can be adjusted for a common or separate AC or DC current supply. Descriptions and application field: This counter combination consists of one hour counter and one pulse counter The counter operates with common current supply, that means the pulse counter registers the connecting frequency and the hour counter the total operating time of a machine/equipment, i.e. oil burner Electromechanical hour counters 920 Mounting type: Flush mounting Counting range: Hour counter: 99999,99 h Pulse counter: ED 100 %, 9999999 Digits character height: 1,5 x 3,5 mm (with lens) Voltages: 115, 230 V AC, 50 and 60 Hz Special voltages (at additional cost): 24 V AC, 50 and 60 Hz Voltage: 24 V DC Connections: Standard: With common current supply At additional cost: With separate current supply, but with same voltage; That means both counters can be separately triggered, order code: E.g. 920/860 (= only for flush mounting) Voltage tolerance: ±10 % Current consumption (common current supply): V AC 3 – 8 mA V DC 7 – 13 mA
