Multifunctional programmable timer
Multi-function programmable timer (MPT) is intended for programming management of various electrical devices with real time reference, such as to turn on/off lights, heating elements, electromechanical products, etc.
There are two options for implementation – single channel MPT and dual channel MPT.
Technical specifications:
1. Current time to display on the display screen (hours: minutes).
2. The maximum error of time the node is not, more than ± 1 sec / day.
3. The current time can be set and adjusted.
4. Entering the program on / off external devices:
- executions of a single channel – 4 programs x1 chanel;
- executions of a dual channel – 2 programs x2 chanel.
Each program is sets on-time t on (h: min) and time off t off (hr: min). The control channel is a “dry” contacts switch- a relay, which removed the outer terminal block MPT and used for switching loads.
5. Power supply 220(-33+22) V AC, 50 Hz.
6. Backup power sentry node by a lithium battery type CR1220 (Ub = 3 V), tentative lifetime is not less than 2 years.
7. Restricting the control channel: – the maximum voltage not exceeding 250 V;
- maximum current, not more than 7 A.
8. Operating ambient temperature range at a relative humidity air 80% – -30…+40 °C.
For reliable operation of the MPT at low temperatures is provided its automatic warm-up, starting with 10 °C.
9. Dimensions, no more – 216x165x45 mm.
10. Weight, no more – 1 kg.
