PES-A02 — KERN relay output module, 5 outputs, 3 tolerance ranges

The PES-A02 is a relay output module for integration with KERN PES/PEJ precision scales, providing five control outputs mapped to three weighing tolerance zones for automated signalling and process control

• Five relay outputs for external control
• Three tolerance zones for precise switching
• Designed for KERN PES/PEJ precision scales
• Compact module, 0.06 kg lightweight build

Precise switching for automated production flows

The relay outputs on this module translate weight results into deterministic control signals, enabling timed actions such as stopping conveyors, triggering signal lamps or actuating valves. With five outputs assigned to three tolerance zones, the module supports clear acceptance, rejection and warning states; this allows programmable process thresholds and reduces manual intervention. The deterministic switching contributes to reproducible cycle times and consistent product quality, which is particularly relevant where traceability and repeatability are required in industrial weighing operations.

Seamless integration with KERN weighing systems

Designed specifically for use with KERN PES/PEJ precision scales, the module offers plug-and-play compatibility where the hardware interface is supported at manufacture. Because the module is not retrofittable, it is intended to be specified with new scales or installed where the original equipment includes the necessary interface. This design decision eliminates ambiguity in field upgrades and ensures electrical and protocol compatibility, reducing the risk of installation errors. The compact housing and low mass make it practical for constrained control cabinets or direct panel integration.

Clear signals that reduce downtime and inspection effort

By converting weighing outcomes into discrete relay states, the module simplifies downstream automation and visual inspection. The clear mapping to three tolerance ranges helps separate marginal results from clear pass/fail conditions, which assists line operators and reduces stoppages for manual checks. Manufactured by KERN with origin in Japan, the module emphasises robust switching behaviour for industrial environments and supports common external devices such as relays, lamps and solenoid valves. The lightweight design and straightforward wiring layout support efficient assembly and predictable serviceability during planned maintenance.

FAQ

What devices can be driven by the relay outputs of this module?
The PES-A02 relay output module from KERN can drive external relays, signal lamps and valves via its five relay contacts, enabling direct actuation or signalling based on weighing results.

Is the module compatible with all KERN scales?
The module is designed specifically for KERN PES/PEJ precision scales; compatibility with other models is not guaranteed and should be confirmed before ordering.

Can the relay output module be added to an existing scale in the field?
The PES-A02 is not retrofittable; it is intended to be specified as part of systems that support the interface at the point of manufacture or initial configuration.

How are the tolerance zones used in practice?
The three tolerance zones provide discrete thresholds for pass, reject and warning states; mapping these to the five outputs allows flexible control logic for automated sorting or process interlocks.
