The Ascon Tecnologic TT 49 is a programmable microprocessor timer with one or two outputs. The device offers the ability to program up to 3 desired time values, 5 operating modes for OUT1 output, 4 operating modes for OUT2 output, 4 time ranges (from max. 9999 hrs. to min. 0.1 sec. ), 4 timing enabled function modes and 2 time counting modes (up and down).
Output 1 operating modes can be:
- delayed mode
- continuous mode
- asymmetric time oscillator start on
- asymmetric time oscillator start off
- single cycle asymmetric oscillator start off
The operating modes of output 2 can be:
- as output 1
- on during counting
- as output 1 with time t3 absolute
- as output 1 with time t3 relatively
The instrument can be connected to an external backup battery (9 V), which allows timing even in case of power failure. A version with internal backup can also be ordered.
The counting status is shown on the four-digit display, while the status of the outputs is indicated by LED lights. The instrument can have 2 outputs (relay or transistor to control a solid state relay - SSR) and 2 digital inputs for timing start (CNT EN) and reset - reset (RES), which can be de-energized or energized (same as the supply voltage).
Programming of the instrument is possible with the three front panel buttons , while timing can be done with the front U button or the digital inputs CNT EN and RES on the rear terminal block.
