Description

CT12 is a programmable device for timing control incorporating 2 independent timers in one case. Two relay outputs (one per channel) control electrical actuators by switching them on and off. A time sequence that may consist of up to 10 ON or OFF periods, each with different duration, may be programmed for each output (channel). The device may be used as a single channel timer with up to 20 period time sequence. After a start command from the featured external input or the front-panel keyboard, the time sequence may be run once or repeated endlessly. A 4-digit digital display indicates current time and – during programming – parameter values, and the keyboard enables setting of all modes and parameters of time sequence. The CT12 timer is easy to program and – with its rich set of features – widely applicable.

(1) Time sequence start and stop may be initiated through external input or keyboard.
(2) Select the active front of external signal
(3) When only the single-channel mode will be used (20-period time sequence), only one (the first) relay may be ordered.
(4) ONLY with isolated power supply!
(5) Ask for availability!
