Complete order number: 6ES7422-1BL00-0AA0
Product Model: SM 422 32DO Digital Transistor Output Module
Compatible systems: Siemens SIMATIC S7-400 full series CPU, S7-400H redundant hot standby control system
Origin: Genuine imported (original factory standard, Germany)
Channel Configuration: 32-channel PNP source-type transistor output, with electrical isolation in groups of 8 channels each, totaling 4 isolated circuits, effectively isolating field faults from the PLC backplane bus
Rated load voltage: DC 24V (Allowable voltage range: 20.4V ~ 28.8V)
Single-channel rated output current: 0.5A; total output current limit for one group of 8 channels: 4A, no overload allowed
Output response delay: typical 0.15ms, supports high-frequency on\/off control
Maximum switching frequency allowed: 100Hz for resistive loads, 2Hz for inductive loads and lighting loads
Protection Design: Each channel features built-in electronic short-circuit pulse protection and reverse polarity anti-misconnection protection, effectively mitigating the risk of module damage due to on-site wiring short circuits
Diagnostic Function: Supports SF fault general indicator, group load power loss, and short-circuit fault status feedback. Module diagnostic information can be read in STEP7
Status Indication: Each channel is equipped with a green LED operational indicator for intuitive monitoring of channel connectivity status
Power supply parameters: Backplane 5V with a maximum consumption of 200mA; module typical power consumption is 4W, and the maximum no-load load side current is 30mA
Wiring accessories: The 40-pin front connector (Model: 6ES7492-1AL00-0AA0) must be selected separately. The module does not include terminal blocks by default
Physical specifications: S7-400 single-slot UR rack-mounted, net weight 0.774kg, protection class IP20
Operating Temperature Range: 0\u00b0C to +60\u00b0C for rack operation, Storage: -40\u00b0C to +85\u00b0C, compliant with industrial EMC anti-interference standards
Product Life Cycle: Discontinued by the original manufacturer, primarily used for spare part replacement in legacy S7-400 projects
Supply Status: Brand-new, factory-sealed, in-stock, with a 12-month warranty, supporting global bulk spare parts supply for international trade<\/p>\n","protected":false},"excerpt":{"rendered":"
