4.2.1 Controller's Tool Signals
The controller is provided with tool signals (i.e., five (5) input signals for sensor, etc.,
four (4) control signals for solenoid valve, etc., DC 24V and DC 24 VGND signals),
which can be connected also from the controller side. (A cable between the controller
and cable is an option.) The relevant signals are described below.

As input signals, no-voltage contacts or transistor open collector inputs are used.
No-voltage contact specifications:
Contact rating: DC24 V, 10 mA or over (circuit current: approx. 7 mA)
Minimum contact current: DC24 V, 1 mA
Contact impedance: 100 Ω or less
Transistor specifications:
Withhold voltage between collector and emitter: 30 V or over
Current between collector and emitter: 10 mA or over (circuit current: approx. 7
mA)
Leak current between collector and emitter: 100 µA or less
