【英文介绍】

Allen-Bradley 1771-IVN is a PLC 5 digital DC input module. It converts the DC signal provided by the user device into the logic level required by the processor. Directly control the status of the corresponding bits in the PLC data table. It offers a modular design with a space-saving and pocket-friendly way to add input to the PLC control system. It has a 1771-WN wiring arm to replace the module, eliminating the need to remove wires. The 1771-IVN is a series C module that supports ½ and 1 slot I/O addressing. It is widely used in the terminal of Sink DC input signal.

The 1771-IVN module has 32 inputs (4 sets of 8) in the voltage class 10-60V DC source (absorbed load). The operating voltage range is 10-30V DC. The typical signal delay is 6ms(±2) at On-DC and 6ms(±2) at Off-DC. It has a maximum on-off current of 1.7mA and a backplane current load of 280mA. Maximum power consumption 15.6W, heat dissipation 53.3 BTU/hr. The 1771-IVN is installed in a 1771 I/O case containing a PLC processor. Between pins 14 and 16 of the lower connector and pins 30 and 32 of the upper connector are the keying bands used to put it into the right slot.

The front panel of the 1771-IVN module has 32 status indicators for the logical side of the system. It has photoelectric isolation to protect system circuits from electrical transients. The 1771-IVN also includes an input filtering function to reduce electrical noise.
