#59, M1S: Two 24V PNP Isolated Open Collector Outputs
Function: Two 24V PNP isolated open collector outputs
Form factor: M1S
Category: Output module
Special needs: ---
Power requirements: 5V/20mA (with both transistors activated)
Output transistors are rated for 24V/0.5A.
To activate a transistor, set the corresponding control line LOW. When left unconnected, control lines default to HIGH (and, hence, the transistors will be closed).
There are two red LEDs connected to the two transistor control lines. The LEDs light up for the LOW state of the control lines (i.e., when transistors are opened).
Typical Connection Diagram
The diagram below shows an external 24V power supply and two loads connected to the outputs of Tibbit #59.
