Digital timer
Price 44.1 EUR no VAT

The TDE4-3/12-24V digital timer is a microprocessor device which is used for switching off and on electrical circuits for a fixed time interval "T" in the range from 0.1sec to 9999min set programmatically. The timer can be started in three ways: a) by turning on the supply voltage; b) by pressing a button on the front panel of the timer; c) by using an external button or sensor connected to the timer. The time-relay has an energy-independent memory. The digital timer is designed for installation in a dashboard (panel montage).

FEATURES

The TDE4-3 digital timer is a compact device on the basis of microprocessor. Used to switch direct current and alternating current electric circuits for a fixed time interval "T", which is set in digital form. The time relay has two operating modes LOG1 (_I¯I_) and LOG2 ( _I¯ ), which allow it to be used in various automated systems. It is used widely in automation of production, technological and other processes.

Non-volatile memory for programmable parameters.
Input for external reset, "Reset" - switch K3 (Fig. 1 and 2).
Input for external start, "Start" - operate with NPN type sensor (Fig. 1) or K2 switch (Fig. 2).
A constant voltage of 11÷23 Vdc (40mA) is provided to power the sensor.
ATTENTION: In “LOG1” mode, when the K2 switch is permanently closed, the timer operates in cyclic mode.
