ADEPT 10330-00500 Speed module

In general, discrete inputs must change state for a minimum of 15 milliseconds for the control to sense and register a change in state. All contact inputs accept dry contacts. Contact wetting voltage is available through terminals 28 and 29. If desired, an external 18-40 Vdc power source can be used for the circuit wetting voltage. In this case terminal 30 (contact input common) must be connected to the external power source’s negative common to establish a common reference point. Each contact input pulls 3 mA when closed and requires at least 14 Vdc to recognize a closure command. See Figure 2-3 for wiring information and 2301D-ST Control Specification for input specifications.

Discrete Input Connections

A positive voltage on any discrete input terminal is sensed by the control as a closed contact or “TRUE” state. With no voltage applied to a discrete input terminal the control senses an open contact or “False” state. For power loading reasons, it is recommended that the control’s internal 24 Vdc not be used to power other external equipment. Discrete inputs with cable lengths greater than 30 meters that are used for critical functions, such as emergency stop, should not be floated in either an on or off state. These inputs should be switched to +24 Vdc or ground.
