The CT-S series is ABB's most economical and universal time relay series. The program includes 16 multi-function and 26 single-function devices with up to 11 functions, which allow for maximum flexibility in use. The devices have 7 or 10 time ranges that can be set from 0.05 seconds to 300 hours. In addition, an extended temperature range of -40 °C to +60 °C is possible for selected devices.
