IC697VAL318隔离模拟量输出模块 英文资料：

IC697VAL318 is an 8-channel 12 bit fully isolated analog output module of GE Fanuc (now Emerson) Series 90-70 PLC platform VAL3xx series. It belongs to the same 8-channel specification as VAL308, with the core difference being the enhancement of output circuit power supply and diagnostic capabilities. It is designed specifically for industrial actuator drivers that require external circuit power supply (Sink/Source) and advanced fault diagnosis.

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 voltage/current signals, drive regulating valves, frequency converters, servo amplifiers, etc., and adapt to actuators that require external power supply.

Power requirements: Backboard+5VDC, requires sufficient power supply such as IC697PWR724/748, supports hot plugging and online configuration.

Manual basis: Belonging to the official manual of the VAL3xx series (GFK-2057), designed on the same platform as VAL304/308/314.

2、 Channel and isolation characteristics

Channel configuration: 8 independent analog outputs, no group sharing, single module fully equipped with 8 points, supporting channel independent configuration.

Isolation level: 1500Vpk electrical isolation between channels and between channels and backboards, completely eliminating common mode interference and crosstalk, suitable for strong interference industrial sites.

Output mode: Supports voltage output and current circuit output, dual switching of hardware jumper and software configuration, compatible with Sink/Source circuit power supply modes.

3、 Accuracy and output range

Conversion accuracy: 12 bit DAC, linearity ± 0.05% FS, zero/gain error can be calibrated by software, high long-term stability.

Voltage range: 0-5V, 0-10V, ± 5V, ± 10V DC, load impedance ≥ 10k Ω.

Current range: 4-20mA, 0-20mA, load impedance ≤ 500 Ω, supports switching between loop power supply and external power supply.

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

4、 Electrical and Diagnostic Protection

Diagnostic function: Advanced channel level diagnosis, supporting output open circuit, short circuit, overcurrent, and overload detection. The fault status can be quickly read through software and trigger an alarm.

Protection mechanism: Built in overcurrent/short circuit protection, reverse connection protection, output TVS tube lightning and surge protection, enhancing module durability.

Power consumption parameters:+5VDC, typical 1.3A (including diagnostic circuit),+15VDC/-15VDC auxiliary power supply. The capacity of the power module needs to be checked in advance.
