Fits multi-sensor liquid and flow panels where you need a GF Signet 9950—two-channel base (expandable toward six sensors), dual 4–20 mA outputs, optional relays with Boolean logic, and ¼ DIN panel mounting.
Key advantages
- Inputs — 2-ch base; up to 6 sensors on -10/-11; frequency / S³L / 4–20 mA via 8058
- Parameters — Flow, pH/ORP, conductivity, salinity, T, pressure, level, DO
- Outputs — Two 4–20 mA standard; expandable
- Relays — Optional mechanical/SSR/binary modules; Boolean logic
- Power — 12/24 VDC or AC/DC options
Typical applications
- Multi-parameter water treatment skids.
- Cooling systems with flow + chemistry.
- Panel builders needing dual loops.
Selection guide
- 2-ch vs 6-sensor base
- Relay module
- DC vs AC/DC power
Common mistakes
- Ordering 9900 when dual channels required.
- Wrong S³L/frequency sensor pairing.
- Exceeding module slot plan.
When to RFQ / what to tell us
- Base code, modules, sensors.
- Quantity, ship-to.
