Siemens SIMATIC S7-300 Digital Output Module (6ES7322-1BH01-0AA0)

Power supply and power consumption parameters

Load voltage (L+): rated value is 24V DC, allowable range is 20.4V DC (lower limit) -28.8V DC (upper limit), suitable for industrial common DC power supply.

Input current: maximum 80mA when powered from load voltage L+(without load), maximum 80mA when powered from 5V DC backplane bus, with moderate load requirements for the power supply circuit.

Power loss: The typical value is 4.9W, which belongs to the conventional power consumption level in industrial modules and is conducive to system heat dissipation management.

Digital output performance

Basic configuration and protection: There are a total of 16 digital outputs with electronic short-circuit protection function. The typical threshold value for short-circuit protection response is 1A. The inductive turn off voltage can be limited to L+(-53V) to avoid damage to the module caused by voltage spikes. It also supports control of digital inputs.

Load and resistance adaptation: In terms of switch capacity, the maximum lamp load is 5W; the lower limit of load resistance range is 48 Ω, and the upper limit is 4k Ω, suitable for various common load types.

Voltage and current: The minimum output voltage for signal "1" is L+(-0.8V), with a rated output current of 0.5A. In environments of 0-40 ° C and 40-60 ° C, the allowable output current range for signal "1" is 5mA (minimum) -0.6A (maximum), with a minimum load current of 5mA. The maximum residual current for signal "0" is 0.5A, and the leakage current control is excellent.

Delay and Switching: When carrying a resistive load, the maximum output delay from "0" to "1" is 100 μ s, and from "1" to "0" is 500 μ s, with a fast response speed; It does not support parallel connection of two outputs to increase current, but supports parallel connection of two outputs to achieve redundant control of the load.

Switching frequency and total current: The maximum switching frequency under resistive load is 100Hz, the maximum switching frequency under inductive load is 0.5Hz, and the maximum switching frequency for inductive load in accordance with IEC 60947-5-1 DC13 standard is 10Hz. The total output current is divided by group, with a maximum of 4A below 40 ° C for horizontal installation, 3A below 60 ° C, and 2A below 40 ° C for vertical installation.

Cable support: Shielded cables can support up to 1000m, while unshielded cables can support up to 600m, meeting the industrial requirements for long-distance cabling.

Interruption and diagnostic function

The module has no alarm function or diagnostic function, specifically manifested as:

No diagnostic alarm, disconnection diagnosis, short circuit diagnosis, fuse melting diagnosis, and load voltage loss diagnosis.

In terms of indicator lights, there is no rated load voltage PWR (green) indicator light and fuse normal FSG (green) indicator light, only a digital output status (green) indicator light, which can observe the output signal status.

Isolation and Connection Design

Potential isolation: Digital output channels have potential isolation function, with every 8 channels forming a group; The isolation between the channel and the backplane bus is achieved through optocouplers, effectively improving anti-interference ability and ensuring the safety of the module and bus.

Insulation test: 500V DC is used for insulation testing, which meets the insulation performance standards of industrial equipment.

Connection method: It needs to be equipped with a 20 pin front connector, with uniform interface specifications for easy installation, replacement, and maintenance.

Physical specifications

Size: Width 40mm, height 125mm, depth 120mm, compact size, can be densely installed in the control cabinet, saving space.

Weight: Approximately 190g, relatively light in weight, with low load-bearing requirements for installation brackets.

Classification and Certification

Classification codes: covering multiple versions of eClass, ETIM, IDEA, and UNSPSC classification codes. For example, eClass 14 to eClass 6 are all coded as 27-24-22-04, ETIM 10 to ETIM 7 are all coded as EC001419, IDEA 4 is coded as 3566, and UNSPSC 15 is coded as 32-15-17-05, facilitating product classification management and procurement identification.

Product certification: With multiple certifications such as CE, EMV, IECEx, FM, ABS, BUREAU, NK (Japan Maritime Association), CCS (China Classification Society), etc., it can be used in hazardous areas and maritime applications, adapting to the industrial and special scene requirements of different countries and regions.
