Pilz PILZ-890120 is a protection unit designed for true power monitoring with a relay that supports 9 different measuring ranges. It features adjustable switching for underload and overload thresholds, along with customizable monitoring reaction time and start-up suppression time. This unit is suitable for DIN rail mounting and operates within an ambient air temperature range of 0 to +55°C. It has a net height of 87 mm and is rated for an 18A measuring current. The safety output contacts ratings vary from 0.1A to 5A at 24Vdc (DC-1; 120W) and 240Vac (AC-1; 1200VA), with lower ratings for DC-13 and AC-15 applications. Connection is established via fixed screw terminal connections. The supply voltage can range from 27.5-264.5Vac for AC and 93.5-287.5Vdc for DC, covering standard nominal voltages. The S1WP sub-range model has dimensions of W22.5mm, a degree of protection of IP40, and operates within a frequency of 0-1kHz for its measuring range. Constructed with a PPO housing, it is designed for both single-phase (1AC) and 3-phase (3AC) input networks, with a rated voltage of 0-120Vac/dc for measuring voltage. The unit's net width and depth are 22.5 mm and 121 mm, respectively, and it has a power consumption of 5 VA. It can be stored in temperatures ranging from -40 to +85°C. The digital outputs include 1 x auxiliary output (SPDT-NO/NC contacts; 0.1-5A 24Vdc 120W DC-1 or 240Vac 1200VA AC-1 resistive load), and it features 1 x analog input for current measurement and 1 x analog input for voltage measurement. Protection functions include underpower and overpower monitoring, complemented by 1 x analog output for voltage and current monitoring.
