F&R F&F Przekaźnik kontroli poziomu cieczy 16A 2P 1-100kOhm 3 sondy (PZ-829 RC)

Liquid level control relay, 16 A, 2P, 1–100 kOhm, 3 probes (PZ-829 RC). Description: On/Off (min/max). The adjustable sensitivity relay PZ-829 is used to detect the presence of electrically conductive liquids in the installation levels of flood probes. It allows you to maintain the minimum and maximum fill level of the controlled liquid within the range set by the user. When the liquid level drops to the MIN state (i.e., the MIN and COM electrodes open), the MIN contact switches to position 11-12; the MAX contact remains in position 8-9. When the MAX state is reached (the MAX and COM electrodes are short-circuited), the MIN relay contact switches to position 11-10 and MAX to position 8-7. Connection: Electrode probes (3 pcs.), connected by a cable with a conductor diameter of up to 1 mm² and a maximum length of 100 m. Terminals 4-5-6 are isolated from the mains. Technical data: Supply voltage 230 V AC, Actuator 2 × relays, maximum load current 2 × 16 A, contact configuration 2 × NO/NC, contact separation yes, sensitivity – adjustable 1 ÷ 100 kΩ, voltage of measurement outputs 6 V, flood probe type 3 x PZ2 connection point, minimum switching time 1÷2 s, switching of the trigger contacts for MAX point max. 5 s. Probe connections are isolated from the mains by a transformer. Connection screw terminals 4.0 mm², tightening torque 0.5 Nm, power consumption 1.1 W, operating temperature -25 ÷ 50 °C, dimensions 3 modules (52.5 mm), installation on a 35 mm rail, protection class IP20.
