Watchdog Timing Relay

Time delay relays are simply control relays with a time delay built in.

Watchdog timing relay.

The watchdog relay can snap on the din rail vertically by hooking the top of the din rail mounting bracket on the top of the din rail then pressing down see the mounting diagrams below. The watchdog relay module is approximately 4 high and 1 wide refer to the mechanical dimensions diagram below. They have a timing range of 0 05 seconds to 10 0 hours.

When designing circuits using time delay relays questions such as what initiates a time delay relay does the timing start with the application or release of voltage when is the output relay energized etc must be asked. During normal operation the computer regularly resets the watchdog timer to prevent it from elapsing or timing out. The multi function version helps reduce your spare parts inventory and standardize your design.

During normal operation the watchdog s internal timer is continually reset by control line activity and its output relay remains energized. Watchdog timers and industrial i o modules since 1988 brentek international has been designing and building watchdog timers standard and custom i o modules pulse timing modules i o racks and i o rack adapters to solve difficult industrial controls applications. If the computer execution halts for any reason the signal it outputs to the watchdog relay coil will stop cycling and freeze in one or the other state.

Watchdog retriggerable one shot time delay relays 1 product time delay relays have timer circuits that control the opening or closing of contacts in a device so they can turn equipment on or off at specific times. Choose between versions with an adjustable time and a predefined function or multifunctional products with four adjustable time ranges and selectable functions. Watchdog timer modules use patented digital or analog timing technology to monitor control system integrity by monitoring the control system s activity by detecting on off transitions of a control line. An easy way to set up such a monitoring system is to have the computer regularly energize and de energize the coil of a watchdog timer relay similar to the output of the recycle timer.

Narrow overall width of 6 2 mm saves space. Bulletin 700 fe economy timing relays are a very narrow 17 5 mm wide. The narrow timer relays are the space saving solution for simple time control applications.
