Why Choose the Finder 8A.88.9.024.1600 OPTA Expansion Module SSR
The Finder 8A.88.9.024.1600 is the SSR (solid-state relay) output expansion for the OPTA smart relay platform. It provides 16 configurable inputs (digital or 0-10 V analogue) and 8 solid-state outputs rated at 3 A DC each, connecting directly to the OPTA CPU via the AUX bus. This module is ideal for control systems that demand fast, silent, and reliable electronic switching.
At a Glance
- Inputs: 16 configurable digital or 0-10 V analogue inputs (set via IDE).
- Outputs: 8 SSR outputs, 3 A DC rating (per channel).
- Supply: 12 to 24 V DC, Class 2 source permitted (under 200 mA typical).
- Interface: AUX expansion port to OPTA main unit; chain up to five modules.
- Mounting: DIN-rail EN 60715, open-type IP20 enclosure.
- Operating ambient: â20  CC to +50  CC, 5 to 95 % RH, altitude ⤠2000 m.
Key Benefits
- High I/O capacity: Adds 16 inputs and 8 outputs in a compact DIN-rail form.
- Fast switching: Solid-state outputs operate silently and reliably with no contact wear.
- Low maintenance: SSR design suits high-frequency and long-life applications.
- Easy integration: Connects directly via AUX bus to the OPTA CPU and is recognised automatically by Finder IDE.

Frequently Asked Questions
How is this product installed or mounted?
It is designed for DIN-rail EN 60715, open-type IP20 enclosure. installation, making it suitable for neat, modular wiring in control panels.
What standards or safety ratings are stated for this product?
Relevant ratings are listed in the technical specifications, including: Operating ambient â20  CC to +50  CC, 5 to 95 % RH, altitude ⤠2000 m.; Low maintenance SSR design suits high-frequency and long-life applications.. Refer to the manufacturer marking and datasheet for variant-specific approvals.
What type of outputs does this module use
Solid-state relay (SSR) outputs rated 3 A DC each for fast and silent switching.
How many expansion modules can I connect to the OPTA CPU
Up to five modules can be connected on the AUX bus to a single OPTA main unit.
What is the difference between 8A.58 and 8A.88
8A.58 uses EMR relays rated AC1 6 A, while 8A.88 uses SSR outputs rated 3 A DC for electronic switching.
Is the module suitable for high-frequency switching
Yes. SSR outputs handle high-frequency or pulse switching better than mechanical relays and require no maintenance.
