Maquet PC1861 Circuit Board Maquet 6651389 Pneumatic Back-plane PC1861 Module Connect Board for Servo s Ventilator

The PC1861 Circuit Board (Part No. PC1861) is the dedicated interconnection hub of the pneumatic section in the Maquet SERVO-s ventilator system. Officially designated as the Pneumatic Back-plane board and protected beneath a metal plate, it carries the connectors to which the gas modules are attached, together with the cable connectors for the safety valve with its pull magnet and the O2 cell. Every breath the SERVO-s delivers depends on this board relaying the pneumatic and electrical links of the inspiratory section reliably. Supplied by Precise as a fully compatible replacement, it is the quiet workhorse that keeps gas delivery, oxygen measurement and safety-valve function firmly in order.

The PC1861 back-plane is an essential spare for hospitals, biomedical service companies and distributors that keep SERVO-s ventilators in daily clinical use. It is the indicated replacement when gas modules are not recognized or communicate intermittently, when the O2 cell produces unstable readings, or when the safety valve pull magnet fails to respond during the pre-use check. Replacing the board is a well-documented service task: the inspiratory channel is removed first, after which the mounting plate is lifted and the gas modules are pulled out to release the board — no exotic tools required.

Pneumatic-Side Specialists — Purpose-built connector layout for the inspiratory section guarantees a correct, gas-tight mating of every gas module.

Safety First — Reliable pull-magnet connection keeps the safety valve responsive, a quiet but vital guardian against overpressure.

Clean O2 Signal Path — Secure O2 cell connector supports stable oxygen measurement for accurate O2 monitoring.

Shielded by Design — Original construction standard matches the metal-plate protection concept of the inspiratory compartment.

Inspected Before Shipping — Connector continuity, insulation and mating force are verified on every single board.
