Product description

The 16-channel, 2-A version must be distinguished from 32-channel, 0.5-A SM 422 variants in the S7-400-I/O family and from other 422 versions. The module measures 25 mm in width, 290 mm in height and 210 mm in depth, dissipates 5 W and weighs approximately 600 g. The documented product data also list 5 V. The documented value for Manufacturer/Order/Identification number is 6ES7422-1BH11-0AA0. Maximum no-load current from L+ is 30 mA, while maximum current consumption from the 5-V backplane bus is 160 mA. The documented product data also list 30. The documented product data also list 160. The documented value for Dimensions is 25 x 290 x 210 mm. The documented value for Power dissipation is typically 5 W. The documented value for Weight is approximately 600 g. The outputs are electronically protected against short circuits, with a typical response threshold from 2.8 to 6 A. The documented value for Short-circuit protection is electronic, typical response threshold from 2.8 to 6 A. Siemens also documents maximum switching frequencies of 100 Hz with a resistive load and 10 Hz with a lamp load. The documented value for Switching frequency is 100 Hz with resistive load; 10 Hz with lamp load. The permitted load-voltage range is 20.4 to 28.8 V DC. The documented value for Voltage range is 20.4 to 28.8 V DC. Siemens product data specifies 16 digital outputs, a 24 V DC load voltage and a rated current of 2 A per output at signal 1. The documented value for Load voltage is 24 V DC. The documented value for Outputs is 16 digital outputs. The specification lists Outputs: 16 digital outputs. The documented value for Output current is 2 A per output at signal 1. The specification lists Output current: 2 A per output at signal 1. Matching the channel groups, isolation, switching frequencies and protection behaviour helps retain the existing S7-400 actuator wiring and control-cabinet design. This distinguishes the S7-400 module from versions with more channels but lower output current. The documented value for Cooling method is passive module heat dissipation within the S7-400 rack. The specification lists Cooling method: passive module heat dissipation within the S7-400 rack. The documented value for Product series is SIMATIC S7-400.
