Why Choose the Finder 99.80.8.230.07 Residual Current Bypass Module?
The Finder 99.80.8.230.07 is a compact and reliable residual current bypass resistor module designed to prevent unwanted relay operation caused by leakage currents in AC control circuits. As part of the Finder Series 99 relay accessories range, this plug-in function module provides an effective solution for suppressing residual currents that can prevent relay coils from fully de-energising in industrial automation, electrical control panels and building control systems.
The module incorporates a bypass resistance that provides an alternative path for unwanted residual current in the relay coil circuit. This helps prevent unintended relay energisation, delayed release and unreliable switching caused by leakage currents from electronic control devices. Its compact plug-in construction simplifies installation into compatible Finder relay sockets without requiring a separately wired external bypass resistor.
Designed for 110–240 V AC control circuits, the Finder 99.80.8.230.07 is suitable for applications using electronic switching devices, PLC outputs and other control equipment where small leakage currents may remain present when the output is switched off. Its socket-mounted design makes it particularly useful in industrial control cabinets, automation systems and electrical installations requiring dependable relay operation.

Reliable Residual Current Suppression for AC Relay Control Systems
Electronic switching devices such as solid-state outputs, semiconductor switches and certain PLC output circuits may allow a small amount of leakage current to flow even when their outputs are switched off. In some relay installations, this residual current can maintain sufficient voltage across the relay coil to cause unreliable release, unwanted energisation or other switching problems. The Finder 99.80.8.230.07 provides a bypass resistance that diverts residual current away from the relay coil, helping ensure that the relay returns to its intended de-energised state.
The Finder Series 99 residual current bypass module is designed for integration into compatible relay sockets, providing a convenient solution without additional external resistor wiring. Its 110–240 V AC operating range makes it suitable for a variety of AC relay control systems. Unlike diode or varistor modules primarily intended to suppress inductive switching transients, this module specifically addresses unwanted residual current in the relay control circuit. Correct socket selection and circuit compatibility should be confirmed before installation.
Typical Applications
- Industrial AC relay control circuits affected by residual leakage currents.
- PLC-controlled relay interfaces and automation systems.
- Electrical control cabinets and industrial distribution panels.
- Relay circuits controlled by semiconductor switching devices.
- Building management and building automation installations.
- Industrial machinery and production equipment control circuits.
- Electronic switching systems where leakage current may prevent relay release.
- Maintenance and upgrading of compatible Finder relay assemblies.

Frequently Asked Questions
What is the Finder 99.80.8.230.07 used for?
The Finder 99.80.8.230.07 is a residual current bypass resistor module designed to suppress unwanted leakage currents in AC relay coil circuits, helping prevent unintended relay operation and unreliable switching.
What operating voltage does the Finder 99.80.8.230.07 support?
The module is designed for 110–240 V AC relay control circuits operating at standard AC supply frequencies of 50/60 Hz.
How does the residual current bypass module work?
The module incorporates a bypass resistor that provides an alternative current path for small residual leakage currents. This helps reduce unwanted voltage across the relay coil when the control output is switched off, allowing the relay to de-energise reliably.
Can the Finder 99.80.8.230.07 be used with DC relay coils?
The Finder 99.80.8.230.07 is specified for 110–240 V AC applications and should not be selected as a DC relay suppression module. DC relay circuits require accessories appropriate to their operating voltage and suppression requirements.
Does the Finder 99.80.8.230.07 include an LED indicator?
No. The Finder 99.80.8.230.07 is a residual current bypass resistor module without an integrated LED indicator. Its primary purpose is to suppress residual leakage currents rather than provide visual relay status indication.
Is the Finder 99.80.8.230.07 suitable for PLC-controlled relay circuits?
Yes. The module can be useful in compatible AC relay circuits controlled by PLC outputs or electronic switching devices where residual leakage current causes unwanted relay operation. The output characteristics and relay socket compatibility should be checked before use.
Where is the Finder 99.80.8.230.07 typically installed?
The module plugs into a compatible Finder relay socket, normally within an industrial control cabinet, automation panel or building control system. Its plug-in construction simplifies installation and replacement.
What is the difference between a residual current bypass module and a diode suppression module?
A residual current bypass module helps prevent unwanted relay operation caused by leakage currents in AC control circuits. A diode suppression module is generally used with DC relay coils to limit inductive voltage spikes generated when the coil is switched off. These modules perform different functions and should be selected according to the circuit requirements.
