Product Description
Red Lion PSMA1000 Interfacing Power Supply Module
The PSMA provides a convenient plug-in answer to those applications requiring electronic sensors or accessories for pulse input to Cub Counters or Ditak Tachometers.
The PSMA is available in 115 VAC primary power input version, and delivers regulated D.C. voltage for sensors and accessories. The signal conditioning amplifier can accept NPN or PNP Open Collector Inputs, or 2-Wire Proximity Sensor Inputs.
SPECIFICATIONS
1. POWER SOURCE: 2 versions, for 115 VAC ±10% 50/6 0Hz, or 230 VAC ±10% 50/60 Hz. (See Ordering Information.)
2. POWER OUTPUT TO SENSORS OR ACCESSORIES: 12 VDC regulated ±5%, 100 mA max.
3. INPUT SIGNAL: (Terminal 3) NPN Open Collector (sink), PNP Open Collector (source), or 2-wire Input. Built-in 3.3 K resistor (Terminal 5) can be jumper connected for pull-up, pull-down, or left unconnected as required. Input Schmidt trigger levels as shown on BLOCK DIAGRAM.
4. OUTPUTS: (Terminal 4) Bi-polar drive to H.S. Input of Cub Counters supplies 100 µsec negative going logic pulse (switches from +3 to 0 volts) in response to a trailing (negative going) edge of the input pulse. This output will drive up to 3 Cub Counters in parallel. (Terminal 8) NPN Loaded Collector to drive the input of Ditaks. The output voltage on this terminal is in phase with the input signal going into Terminal 3. The high level of this voltage will be clamped to 6.2V by the zener diode in the Ditak. This output can drive up to 3 Ditak units.
5. OPERATING FREQUENCY: 0 to 5 KHz with Cub Counters; 0 to 10 KHz with Ditaks.
