HTL to TTL Converters

TTL to HTL /HTL to TTL Converter

TTL to HTL /HTL to TTL converter 1000KHz: This is TTL to HTL or HTL to TTL converter or differential to the single-ended converter or Single-ended to the differential converter. This module receives three differential signals viz +A, -A, +B, -B, +Z, -Z signals (3-10 VDC or 10-24 VDC PP) and converts the differential signal into single-ended signals A, B, Z. Pulse amplitude of output pulses is adjustable from 4.0 VDC to 24 VDC using a preset. In a reverse way, the module receives three signals A, B, Z w.r.t. GND and converts the single-ended signal into the differential signal (+A, -A) (+B, -B) and (+Z, -Z), the differential voltage is adjustable from 4.0 VDC to 24 VDC. Three-point converter is for 3 signals and 2 point converter is for 2 signals.

Procedure to set Output pulse voltage

1)  Connect the 24 VDC power supply to the converter
2)  Connect 5.0VDC at +A and –A for a converter with input pulse 3-8VPP
3)  Put the jumper JP1 on Vs place
3)  Make both supplies ON and connect a voltmeter between terminals +AO and GND
4)  Set the voltage to 5.25VDC by varying the blue preset PR.In clockwise direction voltage increases and vice versa. Check the differential output voltage between +AO and –AO, this will be 0.7V less than the single-ended voltage at +AO and GND
5)  The output voltage is 22.5V if the jumper JP1 is in place 24V
6)  If the 27-30 VDC power supply is available then output voltage 24V can be settable by preset keeping jumper JP on Vs place. This is recommended setting
