831 Series

SPDT, 15 A

Description

The 831 voltage sensor is a single-phase AC voltage sensing device capable of 

monitoring and reacting to overvoltage and undervoltage conditions . This product is 

designed to be wired across terminals A1 and A2 with the voltage being monitored . 

The two LED lamps indicate when the input voltage is present (green LED) and 

when the output is energized (red LED) . 

The Umax dial is used to set the upper trip-point for the voltage sensor . The Umin 

dial is a percentage of the Umax dial and is used to set the lower trip-point for the 

voltage sensor . The timing dial is used to delay the transfer of the contacts, from 

0–10 s, when a set point has been violated .

Application Data

Legacy Time Delay and  

Sensor Relays

Definition

A time delay is a controlled period between the functioning of two events . A time 

delay relay combines an electromechanical output relay and a control circuit . The 

control circuit is composed of solid-state components that control the operation of 

the relay and the timing range . 

Typical time delay functions include: 

 

„

On-Delay

 

„

Repeat Cycle (Starting Off) 

 

„

Interval

 

„

Off-Delay

 

„

Retriggerable One-Shot

 

„

Repeat Cycle (Starting On)

 

„

Pulse Generator

 

„

One-Shot

 

„

On- and Off-Delay

 

„

Memory Latch

Each function is explained in the table on page 31 . Time delay relays offer a broad 

choice of timing ranges from less than one second to many days . There are many 

choices of timing adjustments from calibrated external knobs, DIP switches, thumb-

wheel switches, or a recessed potentiometer .

Principle of Operation

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

is to control an event based on time . The difference between relays and time delay 

relays is 

when

 the output contacts open and close: 

 

„

on a control relay, contacts change state when voltage is applied and removed 

from the coil

 

„

on time delay relays, contacts change state before or after a pre-selected, timed 

interval

Typically, time delay relays are initiated or triggered by one of two methods:

 

„

application of input voltage (On-Delay, Interval On, Flasher, Repeat Cycle, 

Delayed Interval, and Interval/Flasher)

 

„

opening or closing of a trigger signal (Off-Delay, Single Shot, and Watchdog)

These trigger signals can be one of two designs:

 

„

a control switch (dry contact)—for example, limit switch, push button, float switch

 

„

voltage (commonly known as a power trigger)

Definitions

:

 

 Input  Voltage:

 Control voltage applied to the input terminals (see the wiring 

diagrams on page 31) . Depending on the function, input voltage either initiates 

the unit or readies it to initiate when a trigger signal is applied .

  

Trigger Signal:

 On certain timing functions, a trigger signal initiates the unit after 

input voltage has been applied . As noted above, this trigger signal can either be a 

control switch (dry contact switch) or a power trigger (voltage) .

  

Output (Load):

 A time delay relay has an internal relay (usually mechanical) with 

contacts that open and close to control the load . The contacts are represented by 

the dotted lines in the wiring diagrams . 

NOTE

: For the time delay relay to operate properly, voltage must be applied to 

power the load being switched by the relay’s output contacts.

contacts R return to their shelf state . If trigger switch S is closed 

before time delay T is complete, then time is reset . When trigger 

switch S is opened, the delay begins again, and relay contacts 

R remain in their energized state . If input voltage U is removed, 

then relay contacts R return to their shelf state .

Upon application of input voltage U, the relay is ready to accept

contacts R transfer, and preset time T begins . At the end of 

preset time T, relay contacts R return to their normal condition—

unless trigger switch S is opened and closed before before 

preset time T elapses . Continuous cycling of trigger switch S 

at a rate faster than preset time T causes relay contacts R to 

remain closed . If input voltage U is removed, relay contacts R 

return to their shelf state .
