【英文介绍】
Depending on the system model, there are one or two central modules controlled by the microprocessor.
There are two RS485 interfaces on the central module, and the transmission rate can reach 57600bps.
Depending on the system model, there are one or two communication interface modules for serial, Ethernet, or profibus-DP communication.
In case of failure, the central module produces a watchdog signal that can be used to excise Testable output modes
A piece.
One or two power modules (24VDC/5VDC) to provide the 5VDC operating voltage of the central module and the control voltage of the input/output module.
A battery mounted on the back of the rack acts as a backup power source for the real-time clock on the SRAM and central module.
Three 24VDC distribution modules for input and output power supply with protection (fuse) function.
Slots for digital and analog signal input and output (I/O) modules, up to 13 slots.
The 1/O module is directly connected to the central module, and everything you need to connect the I/O bus is integrated in the H41g central module.
Integral cable bracket.
Connect and disconnect 24VDC powered auxiliary modules for watchdog signals, fuses, fan operation monitoring, and two fans.
Diagnostic display and 2 leds for system, 1/O level and user program information.
Two-port RAM for fast access to the second central module. Clock and backup battery
I/O bus logic and connection to I/O modules
Security guard dog
Power monitoring, testable (5V system voltage).
