Supply Original Germany Siemens 6ES7422-1HH00-0AA0 SM422 16-Channel Relay Isolated Digital Output Module 5A 5~230V UC For S7-400 PLC
Complete order number: 6ES7422-1HH00-0AA0
Product Model: SM 422 16DO Relay-type Digital Output Module
Compatible systems: Siemens SIMATIC S7-400 full series CPU, S7-400H redundant hot standby control system
Origin: Genuine German Import (Made in Germany)
Channel Configuration: 16-channel relay passive contact output, with 2 channels per group electrically isolated, totaling 8 independent isolation circuits
Load voltage range: Universal AC/DC UC 5V ~ 230V (AC 5~230V / DC 5~125V), compatible with 24V DC and 220V AC loads
Rated output current per contact: 5A for resistive load, 2A for inductive load; maximum total current of 10A per pair of contacts in each group
Contact type: Passive normally open relay contact, no need to distinguish PNP/NPN polarity, flexible wiring
Maximum switching frequency: 1Hz for resistive loads, 0.5Hz for inductive/lighting loads (not suitable for high-frequency on/off scenarios)
Protection Design: The contact incorporates a built-in surge absorption circuit to suppress high-voltage reverse impact from inductive loads during power interruption
Status Indication: Each channel is equipped with a green action indicator for intuitive monitoring of contact connectivity status; no hardware diagnostic interrupt function
Power supply parameters: Backplane 5V with a maximum consumption of 150mA, module typical power consumption of 4.5W
Wiring accessories: The 40-pin front connector (6ES7492-1AL00-0AA0) must be purchased separately. The module does not include terminal blocks by default
Physical specifications: S7-400 single slot UR rack-mounted, dimensions 25mm×290mm×290mm, net weight approximately 880g
Working environment: Rack operating temperature of 0°C to +60°C, IP20 protection, compliant with industrial EMC anti-interference standards
Supply Status: Brand new, factory-sealed, ready stock available, 12-month warranty, supporting global bulk spare parts supply for international trade
