3701/55 323073-01 functions and interfaces

3701/55 323073-01 is the standard four-channel relay output module for the ADAPT emergency-shutdown system. It contains four configurable trip or logic outputs plus a fifth protection-fault relay. Channels 1 and 2 permit independent or two-out-of-three voting, while channels 3 and 4 use independent voting. Relay behavior follows the fitted hardware, CPU logic and selected energize/de-energize trip arrangement, not merely the part number.

Trip outputsDrive the four configured logic channels according to the validated CPU and relay arrangement.

Voting assignmentDistinguish configurable voted channels from the independently controlled channels.

Protection healthUse the dedicated fault relay to indicate integrity problems separately from machine-trip logic.

Load qualificationReview all simultaneous electrical limits and stricter certified-installation restrictions before connecting field loads.

Installation and selection boundaries

Four-channel output naming excludes the additional protection-fault relay; do not count it as a fifth general-purpose trip channel.
Basic contact limits do not override the lower contact limits required for SIL, CE or hazardous-area installations.
Validate relay energization and voting in the complete shutdown loop before returning the installation to service.

Pre-order check 01

Installation environment

Check the complete 3701/55 323073-01 identity and the actual installation before connection or replacement.

Isolate shutdown output circuits under the approved procedure and identify the current trip state and load wiring.
Verify the intended voting assignment separately for channels 1-2 and channels 3-4.
Review contact voltage, current and power together, including the stricter limits of the actual certified installation.
Check each configured trip output and the independent protection-fault path during the required system validation.

Keep the approved field drawing and installation records available during verification.

Pre-order check 02

Compatibility confirmation

Match the complete component identity with the fitted interfaces and installed configuration.

Module identity: Standard four-channel ADAPT ESD relay output module with an additional protection-fault relay.
Voting: Channels 1-2: independent or 2oo3; channels 3-4: independent only.
Trip behavior: Match energize/de-energize control and normally open/closed field wiring to the validated shutdown design.
Electrical loading: Apply voltage, current and power limits simultaneously, together with SIL, CE and hazardous-area restrictions.
Mechanical integration: Match the relay module position, mating connections and 15.8 × 2.8 × 15.8 cm module envelope.

Confirm 3701/55 323073-01 against the fitted hardware, field wiring and approved commissioning records.
