Technical Specifications Applicable PLC: GE Series 90‑30 Output Channels: 4‑channel analog output Output Signal: 4‑20mA, 0‑10VDC Resolution: 12‑bit Operating Temperature: 0℃ ~ +60℃
Functional Features Digital‑analog conversion for multi‑channel. Independent channel mode configuration. Short‑circuit and open‑circuit fault diagnosis. Backplane bus data exchange.
Application Scenarios Production line actuator control, process control valve regulation, frequency converter set‑point control, Series90‑30 automation projects.
Performance Parameters Output accuracy: ±0.5% FS Load requirement: Follow official load impedance specification
Structural Characteristics Series90‑30 rack‑mount module, LED status indicator on front panel, gold‑plated backplane connector.
Working Principle PLC CPU sends digital setpoint data via backplane bus, DAC chip converts digital signal to analog electrical signal, output to field actuators.
Installation Requirements Insert into Series 90‑30 rack assigned slot. Make full contact of backplane connector. Good heat dissipation environment.
Usage Notes Configure channel output mode in programming software. Do not exceed maximum load impedance. Power‑off operation for module replacement.
