Why Choose the Finder 8A.58.9.024.1600 OPTA Expansion Module EMR
The Finder 8A.58.9.024.1600 is the EMR output expansion for the OPTA platform, adding 16 configurable inputs (digital or 0-10 V analogue) and 8 relay outputs to your OPTA CPU via the AUX port. It is ideal when you need extra field I/O without upsizing your main controller.
At a Glance
- Inputs: 16 configurable digital or 0-10 V analogue inputs (set via IDE).
- Outputs: 8 EMR relay outputs, 6 A AC1 rating.
- 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: −20 °C to +50 °C, 5 to 95 % RH, altitude ≤ 2000 m.
Key Benefits
- High I/O density: 16 inputs plus 8 relay outputs in one compact DIN-rail module.
- Flexible sensing: Each input selectable for digital or 0-10 V analogue operation.
- Seamless integration: Native AUX bus connection to OPTA CPUs; stack up to five modules per system.
- Industrial outputs: EMR contacts rated AC1 6 A for coils and general loads.

Installation note: Connect only to an OPTA CPU via the AUX port. Verify 12 to 24 V DC supply and relay load category (AC1 6 A max). Use interposing contactors for heavy or inrush loads. Maintain −20 °C to +50 °C ambient and IP20 conditions. Do not exceed five AUX modules per system.
Frequently Asked Questions
Are the 16 inputs analogue capable
Yes. Each input can be configured as digital or 0-10 V analogue in the IDE, giving mixed-signal flexibility.
How are the eight outputs rated
Each relay output is rated AC1 6 A (EMR). Use interposing contactors for high inrush or inductive loads.
How many expansions can be added to an OPTA CPU
Up to five modules can be connected on the AUX bus to a single CPU.
What is the operating temperature and enclosure rating
Operating range −20 °C to +50 °C in an IP20 open type housing for DIN-rail EN 60715 mounting.
What is the difference between 8A.58 and 8A.88
8A.58 is the EMR relay version (AC1 6 A); 8A.88 is the SSR version (3 A DC). Both offer 16 configurable inputs.
