Our specialized circuit cards are designed for maximum reliability and simplified installation in security-critical applications.
Available Models
Relay Interface Card (Model OB8B)
The OB8B Relay Interface Card converts low current switch input into a 16-amp interposing relay output, interfacing directly between a control panel or a PLC.
Technical Specifications
-
- Relay Rating: 16-amp interposing relay output
- Mounting: 3.25″ snap track compatible
- Indicators: LED for each energized relay
- Protection: Individual fusing and surge suppression
Key Features
-
- Individual output fusing for enhanced protection
- Relay energized LED indicators for visual status monitoring
- Surge suppression across each relay coil
- Disconnectable field terminal blocks for easy maintenance
- Socketed relays for simple replacement
- Designed to mount to a 3.25″ snap track for standardized installation
Isolated Input Card (Model IB8)
The IB8 Isolated Input Card interfaces and isolates door position switch inputs. This card accepts DRY contacts from any switch input and provides an optically isolated output to a control panel or PLC.
Technical Specifications
-
- Isolation: 2500 volts between input and output
- Compatibility: Accepts any dry contact switch input
- Output: Optically isolated to control panel or PLC
- Mounting: 3.25″ snap track compatible
Key Features
-
- 2500 volts of isolation between the input and output to the controller
- Excellent isolation between Class 1 and Class 2 types of wiring
- Disconnectable terminal blocks for both control and field wiring
- Socketed and field-replaceable opto-isolators
- Designed to mount in a 3.25″ snap track
Audio Relay Interface Board (Model AUDIO8C)
The AUDIO8C Board interfaces directly between a control panel or a PLC, offering specialized features for audio system integration in detention environments.
