Integrating directly into Honeywell Fail Safe Control (FSC) and Safety Manager architectures, the Honeywell 10310/2/1 functions as a specialized DC earth leakage detector to monitor insulation degradation and ground faults. This module continuously evaluates DC distribution systems to detect active ground faults before they escalate into systemic failures or hazardous plant shutdowns. Operating on a nominal 24 VDC power supply, the unit maintains a balanced earth reference of -12 VDC under normal, non-fault operating conditions. Any electrical current imbalance on the DC loop is registered by the internal monitoring circuitry, triggering an output relay once the current leakage exceeds a predefined threshold limit.
| Parameter | Value / Specification |
|---|---|
| Manufacturer | Honeywell |
| Model Number | 10310/2/1 |
| System Compatibility | Fail Safe Control (FSC) / Safety Manager |
| Nominal Supply Voltage | 24 VDC |
| Operating Voltage Range | 18 VDC to 30 VDC |
| Normal Earth Reference | -12 VDC |
| Leakage Trip Threshold | 5.5 mA +/- 1 mA |
| Signal Outputs | Dry contact relay output |
| Contact Power Rating | 1 A at 115 VAC or 100 W at 24 VDC |
| Operating Pulse Frequencies | DC (Normal), 1.0 Hz (Fast), 0.25 Hz (Slow tracing) |
| Mounting Configuration | DIN rail or FSC Rack Interface (Slot positions A5, A11) |
| Shipping Weight (Calculated) | 1.5 kg |
| Package Dimensions (Calculated) | 180 mm x 120 mm x 60 mm |
| Interface Type | Electrical Assignment |
|---|---|
| Rst24 Terminal | Remote manual reset input via standard 24 VDC signal pulse |
| Rst110 Terminal | Remote manual reset input via high-voltage 110 VAC signal pulse |
| Relay Contact Blocks | Potential-free changeover contact for remote DCS or Safety Manager fault registration |
The 10310/2/1 is engineered specifically for Safety Manager and Fail Safe Control (FSC) hardware revisions. While physical slide-in mounting fits standard A5 and A11 slot matrices, verify existing system bus revisions to ensure backplane compatibility with remote software reset calls.
During heavy inductive switching or when system lines feature highly distributed cable lengths, parasitic capacitance can induce transient currents. This dynamic capacitive charging can cause nuisance tripping near the 5.5 mA leakage threshold. Segment the DC distribution if line capacitance consistently breaches typical operational limits.
When utilizing the low-frequency 0.25 Hz pulsed mode to locate localized earth faults in the field, use a low-frequency current clamp paired with a high-impedance digital multimeter. Standard clamp-on sensors often register 0.25 Hz pulses as thermal drift, yielding incorrect readings.
