Safety relays in the PNOZelog product range monitor E-STOP, safety gates or light grids. You can identify the delay-on de-energization units by the v in the product name, e.g. PNOZ e1vp. These can also be used as timers. With the exception of the PNOZ e1p, all units have an AND-OR input for logic interconnections between units. The supply voltage is 24 VDC, the width is 22.5 mm (PNOZ e6.1p/e6vp 45 mm).
