Why Choose the Finder 99.01.0.230.98 LED Indication and EMC Suppression Module?
The Finder 99.01.0.230.98 is a plug-in LED indication and EMC suppression module from the Finder 99 Series. Designed for compatible Finder relay sockets, it combines a green LED indicator with a varistor surge suppression circuit to provide visual indication of relay coil energisation and help limit voltage transients during switching.
Operating across a 110–240 V AC/DC voltage range, the module is suitable for relay control circuits using compatible AC or DC coils. Its plug-in construction allows it to be installed in supported Finder relay sockets without requiring a separate external indication and suppression assembly.
The Finder 99.01.0.230.98 is particularly useful in industrial automation, electrical control panels and machinery control systems where clear coil status indication and suppression of switching-related electrical disturbances are required.
Key Advantages
- Dual-function accessory: Combines visual LED indication and varistor-based EMC suppression in one module.
- Green LED indication: Provides a convenient visual indication when the associated relay coil supply is present.
- Varistor surge suppression: Helps limit voltage transients generated when the relay coil is de-energised.

How the LED Indication and Varistor Suppression Module Works
The Finder 99.01.0.230.98 is designed to operate in conjunction with a compatible Finder relay socket and relay coil. When the appropriate supply voltage is applied to the relay coil circuit, the module's green LED illuminates, providing a visible indication that the coil supply is present.
When an electromagnetic relay coil is de-energised, its stored magnetic energy can generate a transient voltage. The module's integrated varistor helps limit this voltage peak, reducing the electrical disturbance associated with switching the inductive coil.
The varistor provides suppression for compatible AC and DC coil circuits. For DC applications, the positive supply must be connected to the relay coil's A1 terminal to ensure the module is used with the correct polarity.
Unlike a simple LED-only indication module, the 99.01.0.230.98 provides both status indication and transient suppression. The varistor arrangement can also result in only a relatively small increase in relay release time compared with some alternative suppression methods.
The module does not replace the relay, provide an additional switching contact or independently control the connected load. It must be installed with a compatible Finder socket and operated within its specified voltage range.

Frequently Asked Questions
What is the Finder 99.01.0.230.98 used for?
The Finder 99.01.0.230.98 is a plug-in relay accessory that combines green LED coil supply indication with varistor-based EMC suppression for compatible Finder relay sockets.
What is the operating voltage of the Finder 99.01.0.230.98?
The module is designed for a 110–240 V AC/DC operating voltage range.
Does the Finder 99.01.0.230.98 work with both AC and DC?
Yes. The module supports compatible relay coil circuits using either AC or DC supplies within its specified voltage range.
What colour is the LED indicator?
The Finder 99.01.0.230.98 features a green LED indicator that provides a visual indication of the relay coil supply.
Does the Finder 99.01.0.230.98 include surge suppression?
Yes. The module contains an integrated varistor that helps limit voltage transients generated when the associated relay coil is switched off.
What is the difference between a varistor module and a diode suppression module?
A varistor limits voltage peaks and can be used with compatible AC or DC relay coil circuits. A conventional flyback diode is generally used with DC coils and can increase relay release time more significantly.
Which Finder relay sockets are compatible with the module?
Compatible socket examples include Finder 90.20, 90.21, 94.72, 94.73, 94.74, 94.82, 95.63, 95.65, 96.72 and 96.74. Compatibility should be checked against the exact socket and relay configuration.
Does the Finder 99.01.0.230.98 include a relay?
No. The product is an indication and suppression accessory module. A compatible relay and socket are required separately.
Can the Finder 99.01.0.230.98 be mounted directly on a DIN rail?
No. The module is designed to plug into a compatible Finder relay socket rather than mount independently onto a DIN rail.
Is polarity important when using the module with a DC supply?
Yes. For DC applications, the positive supply must be connected to the relay coil A1 terminal in accordance with Finder's connection requirements.
Does the module protect the relay contacts?
The module is intended to suppress relay coil switching transients. It does not replace any additional protection that may be required for inductive loads connected to the relay contacts.
Can the module be used with a 24 V relay coil?
No. The Finder 99.01.0.230.98 is specified for 110–240 V AC/DC. A suitable lower-voltage Finder 99 Series module should be selected for a 24 V coil circuit.
What is the difference between the Finder 99.01.0.230.98 and 99.01.0.230.59?
The 99.01.0.230.98 combines a green LED indicator with varistor suppression, whereas the 99.01.0.230.59 provides LED indication without the same integrated varistor suppression function.
What is the difference between the Finder 99.01.0.230.98 and 99.01.0.230.09?
The 99.01.0.230.98 uses an LED and varistor arrangement, while the 99.01.0.230.09 is an RC suppression module. The correct accessory depends on the required indication and suppression functions.
Can the module be replaced during relay maintenance?
Yes. The plug-in arrangement allows replacement in a compatible relay socket. The circuit must be safely isolated before removing or installing the module.
