Three-channel time relay РВ3
$69 – $72
Three-channel time relay PB3 is designed to count time intervals and automatically turn on or off executive devices at a specified frequency. Has six control buttons: “Stop” and “Pause” for each channel.
Three-channel time relay PB3 is designed to count time intervals and automatically turn on or off executive devices at a given frequency on three channels.
They allow you to start and stop equipment at certain intervals, control various time processes.
The device is manufactured in a panel box and in two power modifications: from an alternating voltage network with a nominal value of 110 ... 240V and from a constant voltage source with a nominal value of 12..24V.
The device allows you to perform the following functions
- automatic counting of time intervals of a given duration on three channels;
- commutation of external electrical circuits;
- displaying the timer time on the LED digital indicator;
- light indication of operating modes;
- control of the device operation by applying external control actions (“Pause” and “Reset” buttons) for each channel separately;
- the ability to change the parameters of the device;
- interface RS-485 protocol (ModBus RTU) (optional).
