#04-5, M1S: Two 24V Isolated Inputs

A green M1S Tibbit.

Function: Two optically isolated inputs with independent terminals. Inputs are fully isolated from the system ground.

Form factor: M1S

Category: Input module

Special needs: ---

Power requirements: 5V/30mA

Mates with: #19, #20, #21

Details

This Tibbit is optimized for the nominal input voltage of 24V. If no external resistor is added, these inputs activate at about 13V. Forward current should not exceed 10mA, which caps the maximum input voltage at about 30V. Add external resistors if you need to apply a higher input voltage.

Combine Tibbit #04-5 with terminal block devices — #20 (nine terminal blocks) or #21 (four terminal blocks).


LEDs

There are two green LEDs connected to the two control lines. The LEDs light up for the LOW state of the control lines (i.e., when current passes through the diodes of the opto-couplers).
