Config Input 4 -
The Config Input 4 setting determines the signal function for the 4th input. Refer to the following
table for selections. For "front panel enable" functions, the indicated functions are only enabled when the input is
applied, all other front panel functions are enabled regardless of the input (with the correct permission level).
Ready Out -
The 'Ready Out' signal indicates the active/idle state of the Controller Module. The output is true when
the Controller Module is ‘ready’. This output is false if the Controller Module is not 'ready'.
Fault Out -
The 'Fault Out' signal indicates a fault has been detected in the operation. This output is complemented,
i.e., the output is true when no fault exists and is false when one or more faults exist.
Config Out 3 -
The Output 3 Config settings determines the signal type for the 3rd output.
Config Output 4 -
The Output 4 Config settings determines the signal type for the 4th output.
Signal Levels
All signals are optically isolated. The power for all signals is provided by the customer’s equipment.
All inputs accept a 24 VDC signal and require 20 mA.
All outputs conduct when the signal is ‘true’ and do not conduct when the signal is ‘false’ (see FAULT OUT). Outputs
can switch a signal of up to 24 VDC and 50 mA. The output consists of the emitter and collector connections to an IC
opto-isolator.
Connections
All connections are through a 37-pin circular plastic connector, with the mating connector (AMP # 206150-1),
backshell (AMP
# 206138-1), pins (AMP # 66105-4), and key (AMP # 200821-1) supplied with the unit. Table 3.1 shows the connector
pin layout.
