Complete order number: 6ES7422-7BL00-0AB0
Product Model: SM 422 32DO Digital Output Module
Adaptation system: Siemens SIMATIC S7-400 full series CPU, S7-400H redundant hot standby control system
Origin: Made in Germany
Channel specification: 32 channels of transistor digital output, 8 channels as a group of electrical isolation, a total of 4 isolation circuits
Load voltage: rated DC24V (allowable voltage range: 20.4V~28.8V)
Single channel output current: rated 0.5A, minimum driving current 5mA, maximum short-circuit protection current 600mA; the total current of each group of 8 channels cannot exceed 4A
Output characteristics: PNP source type output, outputting L+level when signal 1; Output delay of only 0.15ms, high-speed response
Switching frequency: up to 100Hz for resistive loads and up to 2Hz for inductive loads (solenoid valves, contactors)
Protection function: Each channel is equipped with electronic short circuit protection, reverse polarity protection, and overcurrent fuse fault detection
Diagnostic function: supports fault diagnosis of load voltage loss, channel short circuit, and fuse melting, and can trigger hardware diagnostic interruption
Indicator light configuration: green LED status indicator light for each channel; Red fault indicator light on the panel, quickly locate circuit abnormalities
Power supply parameters: Backboard 5V maximum consumption 200mA; no-load load side current 120mA, module typical power consumption 8W
Wiring accessories: A 40 pin front connector (6ES7492-1AL00-0AA0) needs to be selected, and the module does not include wiring terminals at the factory
