*1 The four external input wires are assigned with desired inputs.
Rated no-voltage input: ON voltage 2 V or less, OFF current 0.05 mA or less
Rated voltage input: Max. input rating 30 V or less, ON voltage 7.5 V or more, OFF current 0.05 mA or less
*2 Rated NPN open collector output: Max. 100 mA/ch (20 mA/ch when expansion units are connected), 30 V or less, residual voltage 1 V or less
Rated PNP open collector output: Max. 50 mA/ch (20 mA/ch when expansion units are connected), power voltage or less, residual voltage 2 V or less
*3 Use with the over current protection device which is rated 30 V or more and not more than 1 A.
*4 Does not include the power consumption of the load.
The power consumption with expansion units installed is the total of each amplifier unit’s power consumption.
Example: When using one main unit (IB-1000) with two expansion units (IB-1050) (2400 mW X 1) + (2400 mW X 2) = 7200 mW
