| TECHNICAL SPECIFICATION |
|||
| Supply voltage: | 100 to 240Vac -15%, +10% | ||
| Supply frequency: | 48 to 62Hz | ||
| Power consumption: | 10Watts maximum | ||
| Relay ratings: | Min: 100mA at 12Vdc. Max: 2A resistive at 264Vac | ||
| Leakage current: | The leakage current through the external snubber supplied to suppress voltage spikes on relay contact outputs is less than 2mA at 264Vac, 50Hz | ||
| Over current protection: | External over current protection devices are required that match the wiring of the installation | ||
| Wire size | A minimum of 0.5mm2 or 16awg wire is recommended | ||
| Fusing | Use independent fuses for the instrument supply and each relay output. Suitable fuses are T type, (IEC 127 time-lag type) as follows; Instrument supply: 85 to 264Vac, 2A, (T) Relay outputs: 2A (T). |
||
| Low level I/O: | All other input and output connections are intended for low level signals at less than 42V | ||
| ENVIRONMENTAL RATINGS | |||
| Panel sealing: | The alarm unit is intended to be panel mounted. The rating of panel sealing is defined by EN 60529: IP 65 | ||
| Operating temperature: | 0 to 55 degrees C. Ensure the enclosure provides adequate ventilation | ||
| Relative humidity: | 5 to 90%, non condensing | ||
| Atmosphere: | The instrument is not suitable for use above 2000m or in explosive or corrosive atmospheres | ||
| ELECTRICAL SAFETY | |||
| Safety Standard: | Meets EN 61010, Installation category II, pollution degree 2 Voltage transients on any mains power connected to the instrument must not exceed 2.5kV Electrically conductive pollution must be excluded from the cabinet in which the instrument is mounted |
||
| Isolation: | All isolated inputs and outputs, have a reinforced isolation which provides protection against electric shock. Non-isolated logic connections are electrically connected to the main process variable input, (e.g. the thermocouple) |
