GE Fanuc IC693ALG391F Series 90-30 Analog Output Module (2-channel, current/voltage)
1. Product Overview
The IC693ALG391F is an analog output module in GE Fanuc's (now Emerson Automation Solutions) Series 90-30 family, providing 2-channel D/A conversion. It converts 12-bit digital values written by the CPU into analog current or voltage signals to drive field actuators.
Each channel can be configured for current output (4–20mA or 0–20mA) or voltage output (0–5V or 1–5V). The module requires an external 20–30V DC (nominal 24V) field supply. The field side is optically isolated from the logic side at 1500V, and channels are isolated from each other.
The two channels update synchronously in 5ms. When the CPU goes to STOP, the outputs can be configured to hold last, go to zero, or take a predefined safe value. The module plugs into any 90-30 backplane slot.

6. Why Choose Us
- Exact model match: We verify supply against your full catalog number IC693ALG391F, distinguishing 391 (2-ch output) from 392 (8-ch output) and 221 (4-ch input) to avoid wrong shipment.
- Authorized channel supply: GE Fanuc / Emerson 90-30 modules supplied through regular channels, with product documentation available on request.
- Selection support: We help confirm signal type (current/voltage), channel count, external field power and actuator matching; for 8 channels we can recommend ALG392.
- Delivery & after-sales: Quotation, lead-time confirmation and order follow-up provided; for any parameter questions or alternative options, please contact us by email.
7. FAQ
Q1: Is the IC693ALG391F input or output? How many channels?
A: It is an analog output module with 2 channels, converting digital values to 4–20mA/0–20mA current or 0–5V/1–5V voltage. It is not an 8-channel input; 8-channel high-density output is ALG392, and 4-channel current input is ALG221.
Q2: Which output ranges are available?
A: Each channel selects current 4–20mA or 0–20mA, or voltage 0–5V or 1–5V. Resolution is 12-bit, 4µA/count for 4–20mA.
Q3: Does it need external power?
A: Yes. External field supply is 20–30V DC (nominal 24V); backplane logic draws ~25mA @5V and ~100mA @24V.
Q4: What is the isolation rating?
A: 1500V AC optical isolation between field and logic sides, with channel-to-channel isolation.
Q5: What happens to outputs when the CPU stops?
A: Configurable by software: hold last value, go to zero, or output a predefined safe value to suit process safety requirements.
Q6: What does the -F suffix mean?
A: "-F" is a hardware revision; core function is the same as IC693ALG391. If you actually need an 8-channel or input module, please email us to verify.
