140DDO35300 Schneider Relay Module
140DDO35300 is a 32 point DC discrete output module in Schneider Electric's Modicon Quantum series, designed specifically for industrial automation. It provides 32 independent output channels (4 groups x 8 points) and supports negative logic (trap) output mode. The output voltage is 24V DC, with a maximum output current of 1A for each channel and 4A for each group. The total maximum current of the module is 16A, and it has high-speed response capability (state switching time ≤ 1ms). It supports Modbus RTU communication protocol, has built-in 5A fuses and 3A output point protection, and is equipped with 32 green LED status indicator lights (displaying output status), 1 red LED (detecting external faults), and 1 green LED (displaying bus communication status). The insulation voltage between each channel and the bus is up to 1780Vrms DC (for 1 minute), insulation voltage between groups 500Vrms DC (for 1 minute), operating temperature range -20 ° C to+60 ° C C, The storage temperature range is -40 ° C to+85 ° C, with a power consumption of 1.75W+(0.4V x total module load current), suitable for multiple fields such as industrial automation, control systems, mechanical control, etc.
Technical specifcations for 140DDO35300
Number of output channels: 32 (4 groups x 8 points), each channel is equipped with two types of contacts: normally open and normally closed, which can be flexibly used to control various devices.
Working voltage: 24V DC, capable of providing stable power support for output signals.
Current output capability:
The maximum output current for each channel is 1A.
The maximum output current for each group is 4A.
The maximum output current of the entire module is 16A.
Working temperature range: -20 ° C to+60 ° C, able to adapt to a wide range of industrial environmental temperature conditions.
Storage temperature range: -40 ° C to+85 ° C, ensuring product stability and reliability even when the device is not in operation.
Communication Protocol: Supports Modbus RTU communication protocol, facilitating communication and data exchange with other industrial devices, achieving system integration and automation control.
Status indication:
32 green LEDs are used to indicate input status (1 to 32).
One red LED is used to indicate external fault detection.
One green LED is used to indicate the bus communication status.
Protection function:
The internal output is protected by a 5A fuse.
Each output point also has 3A protection, which can effectively prevent module damage caused by overcurrent and other faults.
Isolation performance:
The isolation voltage between the channel and the bus is 1780V RMS DC, with a duration of 1 minute.
The inter group isolation voltage is 500V RMS DC, with a duration of 1 minute, ensuring the independence and anti-interference ability of the signal.
Response time: The switching time from "off" to "on" and from "on" to "off" shall not exceed 1ms.
Power consumption: 1.75W+(0.4V x total module load current).
