Description
The GS-44 is a GEN II radio transmitter with wired connections for up to 4 voltage or current inputs. Selectable ranges 0-100mV, 0-1vDC, 0-10vDC, 0-20mA, 4-20mA plus EU scaling configured using DARCA software. The GS-44 can also provide a 5 or 12V sensor supply to power sensors from the internal batteries. The GS-44 is supplied with 4 x AA Alkaline batteries and stub antenna.

The GS-44 provides four inputs, A, B, C and D. Each is a voltage or current input. There is also a sensor supply output on Connector 1 and a sensor supply output or Field-Effect Transistor (FET) switch on Connector 2.
0 – Sensor supply output -ve, or FET switch on Connector 2
+ – Sensor supply output +ve, or FET swtich on Connector 2.
V – Voltage input. (0-100mV / 1V / 10V and EU scaling configured using Darca software)
C – Current input. (0-20mA or 4-20mA and EU scaling configured using Darca software). If current is used, link V to C.
