|
| Inputs | | | Analogue: | 1 x Independently controlled trip (open) and close coil current inputs. | | Analogue Accuracy: | <0.5% of fullscale. | | Digital: | 6 x Contact status inputs providing timing of up to 3 main contacts and 3 resistive contacts (‘dry’ contacts).
2 x User configurable input for ‘wet’ or ‘dry’ contact timing (24 - 250V DC or 0V DC). | | Contact Threshold: | 15 - 10,000 ohms. | | Digital Resolution: | 100µSec. | | Connectors: | 4mm safety socket. |
| Outputs | | Coil Operation:
| Solid state outputs for trip (open) and close. | Coil Peak Current:
| 5A (accuracy 2.5mA) or 30A (accuracy 15mA) AC/DC measurement ranges selectable via input sockets.
Other measurement ranges possible via optional external shunt; for example 50A Peak (up to 75mS duration) or 100A Peak (up to 50mS duration). | Coil Max. Voltage:
| 400V peak. |
| Recording | | | Resolution: | 12 bit A/D (1:4096) and 10 kHz sampling rate. | | Recording Time: | Selectable up to 1 second. | | Synchronisation: | All inputs sampled simultaneously. | | Start trigger: | Coil current or selectable on any digital input. |
| General System | Backlit 4 line x 40 character LCD display. Built in printer. Alpha / numeric keypad. RJ45 network port. RS232 serial port.
Audible buzzer. Safety keyswitch to enable / disable coil operation. PS2 socket. VGA port. |
| Real-Time Clock | | | Range: | Time, date, leap year and day of the year with internal battery backup. 100mS resolution. |
| Programming - Settable Parameters | | | User strings: | Site name, breaker number, breaker type, line name and operator name. | | Test times: | Close, Open, Trip Free, Close-Open, Open-Close, Open-Close-Open. | | Coil operate times: | Initial delay, trip coil “on-time”, close coil “on-time”, delay time between closing and opening, delay time between opening and closing. |
| Computed Results | | Up to a sequence of 3 operations detailing 3-phase information: | | Peak coil current, operate times and operate time spread (main / resistive), bounce time. |
Operating Voltages | | | Prime Power: | 100 to 370V DC, 90 to 264V AC auto-sensing via IEC power connection. Burden <20 VA. |
| Environmental | | | Operating Temp.: | -20ºC to +70ºC (-4ºF to +158ºF) | | Humidity: | 0 to 97% RH non-condensing. | | Isolation: | 2kV rms for 1 minute (channel to channel, channel to earth). | Surge Withstand:
(Transient) | To IEC 801-5. 1.2/50mS.
Common Mode: Severity level class 4. Series Mode: Severity level class 3. | | Fast Transient Burst: | To IEC 801-4 level 3. | | RFI Immunity: | To IEC801-3 level 3. 10V/m 26-1000MHz. | | Emissions: | To EN50081-1: 1992. |
