Time relay eight-channel РВ8

The eight-channel time relay PB8 is designed to count time intervals and automatically turn on or off executive devices at a given frequency on eight 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 is supplied complete with an output expansion unit BR8, to which output devices are connected. The control buttons are connected to the time relay, and the output devices are controlled via the RS-485 interface (ModBus RTU protocol) and the BR8 output expansion unit.

The device allows you to perform the following functions

• automatic counting of time intervals of a given duration on eight 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;
• RS-485 interface protocol (ModBus RTU) for control of output devices via BR8.
