GP420 DUAL TRIP AMPLIFIER

GP420 Dual Trip Amplifier

The GP420 is a member of the Elcontrol 'GP' series of general-purpose trip amplifier cards. The GP420 can accommodate two plug-in trip amplifier cards from the Elcontrol SPL180 range. ln addition, there is the option of a signal conditioning card providing analogue current-loop signal strength outputs (0-10mA or 4-20mA) for each of the two trip amplifiers

Product description

The GP420 is a member of the Elcontrol 'GP' series of general-purpose trip amplifier cards. The GP420 can accommodate two plug-in trip amplifier cards from the Elcontrol SPL180 range. ln addition, there is the option of a signal conditioning card providing analogue current-loop signal strength outputs (0-10mA or 4-20mA) for each of the two trip amplifiers (this is only applicable to certain amplifier types - contact Elcontrol engineering for details).

The GP420 provides a flexible choice of output relay configurations:

Each flame amplifier card may operate its own relay.

One relay may be configured to operate if either amplifier card is sensing flame ('OR' mode), the other only if both are sensing flame ('AND' mode).

For trip amplifiers offering a 'fault' or 'alarm' output signal, one of the relays may be assigned to this function, and the other to operate in 'AND' or 'OR' mode as previously described.

The GP420 may be fitted in an ABS enclosure, with protection classification to lP65, or in the Elcontrol UVH6/FP range of Group llB Flameproof housings.
