4. Product Introduction
The Eagle Signal CX312B6 (Danaher Controls) is a microprocessor-based solid-state timer/counter from the CX300 Cycl-Flex series. It provides reliable digital timing and counting functions with an LCD display and panel-mount design.
Maintenance and controls engineers use this unit for machine sequencing, process timing, and count-based control in industrial equipment. It offers both a high-current DPDT relay output and a solid-state output, along with an inhibit input. As a legacy product, available units are typically New Surplus or residual stock.
5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No display or power | Supply voltage missing or incorrect | ✅ High | Measure 240 VAC at power terminals | Verify correct supply voltage and wiring |
| Outputs do not energize | Programming or inhibit active | ✅ High | Check inhibit input status and mode settings | Confirm timing/count parameters and inhibit signal |
| Incorrect timing or counting | Wrong mode or setpoint | ✅ High | Review front-panel settings and mode selection | Re-enter correct time/count values |
| Relay chatters or fails | Overload or contact wear | ✅ Medium | Check load current against 10 A rating | Reduce load or replace unit if contacts are damaged |
| Unit resets unexpectedly | Noise or power interruption | ✅ Medium | Check power quality and grounding | Improve supply filtering if needed |
If the issue persists, record the current mode, setpoint values, and LED/display status before contacting support.

6. Frequently Asked Questions (FAQ)
Q: Who manufactures the CX312B6?
A: It is an Eagle Signal product under the Danaher Controls brand (CX300 Cycl-Flex series).
Q: What outputs does the CX312B6 provide?
A: It has a 10 A DPDT instantaneous relay output and a 1 A solid-state output.
Q: Is this timer still in production?
A: It is a legacy industrial timer. Current availability is primarily New Surplus or residual stock from earlier production.
Q: Can I replace it with a modern digital timer?
A: In many cases yes, but you must match the voltage, output type, timing range, and mounting style. Verify pinout and functionality before substitution.
Q: What is the inhibit input used for?
A: The 120 VDC / 120 VAC inhibit input allows external control to pause or hold the timing/counting function.
Q: Why is pricing lower than a new industrial timer?
A: This is a discontinued or low-volume legacy model sold as New Surplus or residual stock. Pricing reflects remaining inventory rather than current production cost. All units are functionally verified before shipment. Standard warranty is typically 12 months.
Q: Is the unit panel-mount only?
A: Yes, it is designed for panel mounting with an LCD display for local setpoint and status viewing.
