ABM

The ABM Active Burden Module is designed for application with solid state status inputs wherever high security signaling is required.

The ABM is intended to be used with digital relays and related products such as RTU’s as an aid to improve electrical transient and noise immunity.  In particular, for added immunity against infrequent and irregular transientssuch as represented by the capacitor discharge test as defined in standardENA TS 48-4.

In normal operation, the ABM imposes a short term increased burden to the operate signal which is then removed after approximately 50 ms.

The ABMZ version is a special version that provides a minimum voltage pick-up threshold.

Use the ABM Demonstrator to check status input susceptibility and compare improvements using an ABM or a shunt resistor.

‘Screw terminal’ and ‘Flying lead’ versions are available as depicted.
