PILZ-837285 Pilz Voltage Relays

Pilz PILZ-837285 is a protection unit designed for 3-phase voltage monitoring, including overvoltage and undervoltage monitoring functions. It is suitable for DIN rail mounting and operates within an ambient air temperature range of -15 to +55°C. The unit has a net height of 87 mm and supports safety output contacts ratings from 0.1A to 5A at 24Vdc (DC-1; 120W) and 1.5A at 24Vdc (DC-13) with fixed screw terminal connections. The S3UM sub-range model features dimensions of W22.5mm x D122 mm, an IP40 degree of protection, and a supply voltage range of 20.4-26.4Vdc (24Vdc nominal). It operates at a frequency range of 40-400Hz, with a power consumption of 1.5 W, and is constructed with a PPO housing. This unit is designed for a 3-phase (3AC) input network with a rated voltage (AC) of 500/550Vac measuring voltage and a net width of 22.5 mm. It offers operating modes including fault latching/non-latching and normally energized/de-energized modes, with an ambient air temperature range for storage of -40 to +85°C. The device includes 1 x delayed auxiliary output (SPDT-NO/NC contacts; 0.1-5A 24Vdc DC-1 resistive load; 0.5-10s time-delay selectable) and 1 x analog input for L1-L3 voltage measurement. Protection functions cover undervoltage, overvoltage, phase sequence, phase failure, and asymmetry, with 1 x automatic reset and 1 x switching commutation digital inputs.
