PILZ-837290 Pilz Voltage Relays

Out if stock but available for backorder.

Pilz PILZ-837290 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 240Vac (AC-1; 1200VA) and 2A at 230Vac (AC-15). Connection is facilitated through fixed screw terminal connections, and it requires a supply voltage of 20.4-26.4Vac (24Vac nominal) within the S3UM sub-range. Dimensions include a width of 22.5mm and a degree of protection rated at IP40. The frequency measuring range is 40-400Hz, and it is housed in a PPO material. Designed for a 3-phase (3AC) input network, it has a rated voltage for measuring of 208/400/480Vac, a net width of 22.5 mm, and consumes 1.5 W of power. The net depth is 122 mm. Operating modes include fault latching or non-latching and normally energized or de-energized modes. It can be stored in temperatures ranging from -40 to +85°C. The unit features 1 x delayed auxiliary output (SPDT-NO/NC contacts; 0.1-5A 240Vac AC-1 resistive load; 0.5-10s time-delay selectable for ON-delay energization), 1 x analog input for L1-L3 voltage measurement, and protection functions against undervoltage, overvoltage, phase sequence, phase failure, and asymmetry. Digital inputs include 1 x automatic reset (Y1-Y2 linked) and 1 x switching commutation (Y2-Y3).
