Operating instructions for the Signet 9950 Dual Channel Transmitter, covering installation, wiring, configuration, and maintenance of a two-channel…
The Signet 9950 Dual Channel Transmitter is a versatile instrument designed to support two sensors of the same or different types in one unit. It supports sensor inputs for pH/ORP, Conductivity/Resistivity, Salinity, Temperature, Pressure, Level, Dissolved Oxygen, and devices transmitting a 4-20 mA signal via an optional converter. The device features advanced capabilities including derived functions (sum, delta, ratio), multiple relay modes, and timer-based relay activation.
The instrument requires regulated 12 to 32 VDC, ±10%.
The maximum current draw is 500 mA with DC power.
The module includes four mechanical relays rated at 5A, 250 VAC or 5A, 30 VDC.
