RS2020 - Relay Standard


The Applied Relay Testing RS2020-001 Basic Relay Standard provides a range of switchable relay types with assured operate and release characteristics and is used to verify that a relay parametric test system is operating within its specification.

In essence a virtual relay, the user, by means of front panel switches, can define the following parameters:
  • The relay type:
    Monostable single coil
    Bistable single coil
    Dual coil
  • Operate and release voltages - independently user programmable
  • Coil resistance loads - user selectable:
    100 Ohms
    1k Ohms
    Open circuit
  • Coil suppression diodes - user selectable
    Single diode
    Double diode
  • Coil polarity - user selectable:
    Normal
    Inverse

In use, the RS2020-001 is connected to the relay parametric test system under test. The RS2020-001 is user programmed with the parameters it is to emulate, i.e.:

Monostable relay
Vop=14.8V
Vrel=9.7V
Rcoil=1k Ohms
Single coil suppression diode

The relay parametric test system is then used to 'test' the RS2020-001. The results generated by the relay test system are then used to verify that the relay test system is operating correctly. The addition of front panel test points and a manual override facility, facilitate testing and calibration of the RS2020-001 unit itself.
