Logical inputs
The input module has 6 inputs, with 5 inputs on the Control module.
The no-voltage inputs must be controlled by applying an external voltage (usually the auxiliary power
voltage).
Refer to the insertion diagrams for the hookup scheme.
Each input has the following configurable parameters:
• Logic: DIRECT (active when the input is powered), or INVERSE (active without voltage to the input).
• Trip delay (IN1-1 tON, IN1-2 tON... IN1-6 tON) and drop-out delay (IN1-1 tOFF, IN1-2 tOFF... IN1-6
tON ).
• Mapping functions to the input module inputs (IN1-1...IN1-6).
[1]
The Trip and Deactivation timer settings provide for inserting a programmable delay on input signal
transitions; in particular, the positive transition is considered valid only if the input remains stably
active for at least the programmed delay
t
ON
; in the same way, for negative transitions, the input must
remain inactive for at least the programmed delay
t
OFF
.
Each logical input on the input board (IN1-1...IN1-6) can be mapped to one of the default functions
listed below. The parameters can be set in the menu
Set \ Input board inputs.
