Low Voltage Output Connections
The DLC-XP control offers one Analog (e.g., 4-20mA) output, and two Transistor-based digital ouputs.
The Low Voltage Output connection block is labeled J5 'OUTPUT' (refer to Figure 7). It contains
three-pairs of outputs: Analog, Alarm and Motor Control Signal.
The Transistor based Dry Contact output is optically isolated. It is not self-powered to achieve total
isolation. The external device must supply and detect a return voltage level. The maximum voltage
capability of these outputs is 24 VDC.

Analog Output (DLC-RC)
The Analog Output Channel follows the actual stroke length position. It is calibrated to source
current in the 0 to 20mA range (e.g., 4-20mA). Refer to the Section 7 – General Operation:
Calibration for further details.
The Analog Output is used to control slave devices (e.g., DLC's, ELMA's, PULSAMATICs, etc.) or
to fulfill closed loop system requirements. Attach the connection points labeled '1-CURRENT(+) and
'2-CURRENT(-)' on connector J5-OUTPUT (see Figure 7) to the external device. Attach the Positive
lead to position 1 and the Negative lead to position 2. The analog output will drive against a
maximum load of approximately 700 ohms. The Analog Output is isolated from all other inputs,
outputs. and earth ground. Refer to the instructions in Section 7 – General Operation: Calibration
for Analog Output Calibration.
