Why Choose the ABB CT-WBS.22S Impulse & Flasher Timer?
The ABB CT-WBS.22S is an electronic impulse and flasher time relay from the ABB CT-S timer range, designed to provide flexible timing and switching functions for industrial automation and control systems. It combines 7 selectable timing functions with two changeover relay outputs, providing a versatile solution for timed switching, pulse generation and flashing applications.
The CT-WBS.22S provides 10 selectable time ranges from 0.05 s to 300 h and operates from a rated control supply of 24–48 V DC / 24–240 V AC. Its front-face operating controls allow precise adjustment of the selected timing function, while two LEDs provide indication of operational states.
The timer features 2 c/o (SPDT) relay contacts rated at 250 V / 4 A. The CT-WBS.22S uses screw connection technology with double-chamber cage terminals and a compact 22.5 mm wide housing designed for DIN rail installation in industrial control panels.
