Pilz PILZ-837250 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 is designed with a 40 percent hysteresis. It features safety output contacts ratings of 0.1A-5A at 24Vdc (DC-1; 120W) and 1.5A at 24Vdc (DC-13). The connection type is fixed screw terminal connections, and it falls under the S3UM sub-range. Dimensions include a width of 22.5mm and a degree of protection rated at IP40. The supply voltage requirement is 20.4-26.4Vdc (24Vdc nominal), with a frequency measuring range of 40-400Hz. The housing is made of PPO material, and it is designed for a 3-phase (3AC) input network with a rated voltage (AC) of 100/110Vac measuring voltage. The net width is 22.5 mm, and it has a power consumption of 1.5 W with a net depth of 122 mm. Operating modes include fault latching/non-latching and normally energized/de-energized modes. The ambient air temperature for storage ranges from -40 to +85°C. It features 1 x delayed auxiliary output (SPDT-NO/NC contacts; 0.1-5A 24Vdc DC-1 resistive load; 0.5-10s time-delay selectable (ON-delay energization)), 1 x analog input (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).
