The 140 ERT 854 10 is an intelligent 32 point input module for Quantum that allows full configuration of inputs and evaluates the input signal status every 1 millisecond.
The 32 inputs are designed for input voltages of 24 to 125 VDC and are distributed in 2 independent groups. Each group is supplied with a separate external reference voltage (typically 24, 48, 60 or 125 VDC), to influence the threshold limit and minimum current consumption. The module status Ready, Active and Error as well as the input status (status of the terminals) are clearly displayed by the status LEDs on the module.
NOTE: The reference input voltage must be identical to the input voltage level.
140 ERT 854 10 firmware processes inputs in four separate configurable function blocks with 8 inputs which support the following functions that can be selected.
-
Binary inputs: input values are sent cyclically to the PLC.
-
Event inputs: Time registered event logging for 1, 2 or 8 processed inputs, with 5 byte time register, integrated FIFO buffer for 4096 events and acknowledging PLC transfer by the user.
-
Counter inputs: 32 bit addition of processed events up to 500 Hz that are transferred cyclically to the PLC.
Parameters can be set for processing individual inputs: (disabled, inverted, and with debouce filter). A configurable chatter filter can be activated for the event and counter inputs and event edge monitoring carried out.
The module clock requires a time synchronization signal and provides a 24 VDC input with potential isolation for the following standard time receiver with DCF 77 format.
The ERT internal software clock can alternatively be created by the application program, or be free running.
The ERT data evaluated can be buffered with a maximum current consumption of 0.07 mA by the 140 XCP 900 00 battery module in the event of power loss.
