Relay PCA 04523

Addendum to E-Series Operator Manuals

There are two versions of the new relay card. Table 1-1 above cross references the PCA version with the various E-series analyzer models.

1.3.1. Version 045230200

This is the most commonly used version of the Relay PCA. It includes a bank of solid state AC relays. This version is installed in analyzers where components such as AC powered heaters must be turned ON & OFF. A retainer plate is installed over the relay to keep them securely seated in their sockets.

1.3.2. Version 045230100

This is the base version of the Relay PCA. It does not include the AC relays and is used in instruments where there are no AC powered components requiring control. A plastic insulating safety shield covers the empty AC Relay sockets (See Figure 1-3)

CAUTION

Never remove this safety shield while the instrument is plugged in and turned on. The contacts of the AC relay sockets beneath the shield carry high AC voltages even when no relays are present
