Yokogawa SAI533-H33 Analog Output Module

Powerful signal conversion: Converts digital signals into analog voltage or current signals (common outputs: 4-20mA or 0-5V), enabling precise control of machinery and equipment to operate according to preset programs.

High reliability: With mature design, strict component selection, and standardized manufacturing processes, the module ensures stable operation in various complex and harsh industrial environments.

Multi-channel output: Equipped with 8-channel analog output, it can control multiple devices or actuators simultaneously, enhancing system integration and control efficiency.

HART communication support: Enables communication with HART-protocol devices, facilitating operations such as parameter setting and status monitoring.

Output signal: 4-20mA

Number of channels: 8 channels

Isolation method: Isolated module

Standard: ISA standard G3

Operating temperature: -20°C to 70°C

Accuracy: ±16µA

Allowable load resistance: 0 to 750Ω

If the output signal does not match the set value, the module range may be incorrectly configured.
Solution: Check and reset the range parameters.

Internal circuit failure may occur.
Solution: Verify the module power supply. If the power supply is normal, internal chips or circuit components may be damaged; contact professional maintenance personnel.

When unable to communicate with HART devices, first check if the communication cable is connected correctly and whether the HART address of the device matches the module configuration.
Solution: Reset the address to ensure consistency.

Confirm whether communication parameters (e.g., baud rate, parity) are correct.
Solution: Reset parameters according to device requirements.

Overheating may result from high ambient temperature or poor heat dissipation.
Solution: Install the module in a well-ventilated area without obstructions; add a heat dissipation device if necessary. Prolonged operation in high temperatures may affect performance or cause damage; improve the working environment temperature.

Indicator lights reflect the module's working status. If the power indicator is off, check the power supply and connections.
Solution: Ensure the power supply is normal and wires are firmly connected.

If the fault indicator lights up, a severe internal fault may exist.
Solution: Power off and restart the module. If the fault persists, contact the manufacturer's after-sales service or professional maintenance personnel.
