Product Introduction
The CAMOS 6809TAM 25-2431 is a binary and analog data acquisition unit from the Stein Sohn Camos 6809 series. It serves as a communication and power conversion module in industrial monitoring applications, commonly found in marine, reefer container, or specialized process systems.
In field use on Camos 6809 racks, this unit handles signal acquisition while providing regulated DC outputs from a wide 18-36 VDC input. Engineers choose it for direct compatibility with existing Camos installations where replacement parts remain limited due to the age of the platform.
Installation & Configuration Guide
Stage 1: Pre-Installation Preparation (10-15 minutes) ⚠️ Safety First: Notify operations, initiate controlled shutdown, apply lockout/tagout on the 18-36 VDC supply, and wait 5 minutes for capacitors to discharge. Tools Required: Grounded ESD wrist strap, PH1 or PH2 screwdriver, digital multimeter, wire labels, and a smartphone for documentation photos. Data Backup: Photograph all connected wiring, terminal layouts, and any DIP switch or jumper settings. Record existing module serial numbers and system status before removal.
Stage 2: Removing the Old Module
- Remove the front cover or bezel if present.
- Label each wire or terminal block position clearly.
- Disconnect wiring carefully — do not pull on wires; release terminals properly.
- Release the locking tabs or screws and pull the module straight out to avoid damaging backplane connectors.
- Inspect the rack slot for bent pins, corrosion, or dust.
⚠️ Note: Keep the old module nearby as a physical reference until the new unit runs without faults.

Stage 3: Installing the New Module (10 minutes)
- Put on your ESD strap and work on a grounded surface. Confirm the replacement matches CAMOS 6809TAM 25-2431 exactly.
- Replicate any board configurations (E169.1 series) from your photos.
- Align and insert the module into the slot until it seats firmly with an audible or tactile click. Secure locking tabs.
- Reconnect wiring exactly as documented, using proper torque on terminals.
Self-Checklist: [ ] Configurations match, [ ] Wiring verified and secure, [ ] Module fully seated and locked.
Stage 4: Power-On & Testing (15-20 minutes) Pre-Power Check: Use a multimeter to verify no shorts on the DC input rail. Power-On Steps:
- Energize the rack power supply only — leave field devices disconnected initially.
- Observe power LEDs and communication status indicators. Normal operation shows stable power LEDs without persistent fault lights.
- Verify output voltages: 5 VDC, +12 VDC, and -12 VDC within tolerance.
- Reconnect field signals and perform dry-run testing of binary and analog channels.
- Monitor system communication handshake with the Camos 6809 master.
⚠️ Troubleshooting Note: If power LEDs fail to illuminate, double-check input voltage polarity and connections. Persistent communication errors often trace back to mismatched board variants or wiring shield grounding. If the unit draws excessive current, verify total rack load does not exceed supply capacity.
Frequently Asked Questions (FAQ)
Can this module be hot-swapped under power? No. The CAMOS 6809 design does not support hot-swapping. Removing or inserting the module while powered risks damaging the backplane or the unit itself. Always remove power first.
Is the CAMOS 6809TAM 25-2431 obsolete, and is the stock genuinely new? Yes, the Camos 6809 series is long obsolete from the original manufacturer. Units offered as new surplus come from unused OEM or distributor stock. We perform full inbound inspection and functional testing before shipment. Test reports and photos are available on request.
What is the direct replacement if this exact model is unavailable? No current-production direct drop-in exists from major DCS/PLC brands. Compatible spares are limited to other Stein Sohn Camos 6809 family modules with matching E169.1 board variants. Confirm pinout and firmware compatibility before ordering alternatives.
Will I lose configuration or programming when swapping the module? The TAM 25-2431 is primarily a data acquisition and power/communication unit, not a CPU holding user logic. Configuration data typically resides in the main controller. You should not lose logic, but always back up the full system beforehand.
Why is the price lower than original factory list pricing? Because this is new surplus stock rather than current-production OEM parts. The series is discontinued, so pricing reflects availability from remaining inventory rather than new manufacturing. All units undergo verification testing to ensure functionality.
What warranty do you provide on this module? We offer a 1-year functional warranty from shipment date, covering defects in materials or workmanship under normal operation. Warranty does not cover damage from improper installation, ESD, or exceeding specified ratings.
