3. Connecting and Configuring Probes
3.1. Configuring Analog Sensors
In its standard configuration, the 2300 has four 4-20 mA (analog) inputs. The rear-side block
connectors are shown in Figure 5 above. Wiring of a sensor depends on whether it is loop
powered or externally powered; variations are shown in Figure 6.
1. If the probe is to be loop-powered, then its black (negative) wire connects to the
chosen AN-IN-x (where x is 1, 2,3, or 4) terminal and the red (positive) wire connects to
one of the 24V terminal.
2. If the probe is externally powered such as from a transmitter, then its red (positive)
wire connects to the externally to the chosen AN-IN-x terminal and the black
(negative) wire connects to the ground (GND) terminal.
3. If the probe has three wires, it needs an external power supply: refer to the probe
directions for hookup.
Figure 6 - Possible analog probe wiring diagrams. There are other possible three-wire probe setups,
so please refer to your specific probe’s instructions for proper hook up.
3.2. Connecting Pulse Rate Output Sensors
The 2300 has inputs for 3 pulse rate sensors. These are typically flow sensors that output a
sinusoidal or square wave, e.g. paddlewheel and magnetic flow meters. The contacts D1 and
D2 are high precision optically isolated frequency counters, while D3 is not isolated. D3 uses a
one-second count of the pulse rates to determine frequency.
