IC697VAL304 数字输入模块 英文资料：

IC697VAL304 is an 8-channel 12 bit isolated analog output module on the GE Fanuc (now Emerson) Series 90-70 PLC platform, belonging to the VAL3xx series. It is designed specifically for voltage/current circuit control in industrial sites that require high isolation between channels. It is often mistakenly labeled as a digital module but is actually a high-precision analog output component.

1、 Core positioning and compatibility

Platform ownership: Series 90-70, compatible with RX7i PACSystem, 6U VME bus configuration, occupying 1 rack slot.

Core application: Convert PLC digital signals into standard analog signals to drive actuators such as regulating valves, frequency converters, servo amplifiers, etc.

Compatibility: Requires sufficient power supply such as IC697PWR724/748, supports hot swapping and online configuration.

2、 Channel and isolation characteristics

Channel configuration: 8 independent analog outputs, fully equipped with 8 points per module, no need to group and share resources.

Isolation level: 1500Vpk electrical isolation between channels and between channels and backboards, completely eliminating common mode interference and crosstalk.

Output type: Supports voltage output and current loop output, switched through hardware jumpers or software configuration.

3、 Accuracy and output range

Conversion accuracy: 12 bit DAC, linearity ± 0.05% FS, high output stability, meeting conventional process control requirements.

Voltage range: covering 0-5V, 0-10V, ± 5V, ± 10V DC, suitable for most voltage control scenarios.

Current range: Supports standard industrial current circuits of 4-20mA and 0-20mA, with circuit power supply capability.

Response time: Typically ≤ 1ms, meeting the real-time requirements of medium and high-speed closed-loop control.

4、 Electrical and Protection

Load capacity: Voltage output ≥ 10k Ω, current output ≤ 500 Ω, compatible with mainstream actuator impedance.

Protection function: Built in overcurrent and short-circuit protection, output open circuit detection, fault status can be read through software.

Backplane power consumption:+5VDC, typical 1.2A,+15VDC/-15VDC auxiliary power supply, power module capacity needs to be checked.

5、 Installation and Environment

Wiring method: Front end screw terminal, supports shielded cables, recommended double ended grounding to reduce electromagnetic interference.

Environmental indicators: working temperature -20 ℃~+70 ℃, humidity 5% -95%, no condensation, vibration and impact resistance in accordance with industrial standards.
