Operating Instructions

Connection

1: Power supply + (24 V DC)

2: Power supply - (24 V DC) / Ground

3: Analog Input - (Ground)

4: Analog Input + (current 0/4-20mA or voltage 0-10V or 0-400 mV)

5:

6: Relay 1

The optional relay2 has tree 2.8mm flat connectors on the top of the module (KTE-version two

7: Relay 1

screw terminals).

8: Relay 1

Adjustment of Switching Limits, Status-LEDs

The two thresholds “low” and “high” are adjusted via two front-plate potentiometers. Three status LEDs show the

position of the input: input values below “low” threshold, between “low” and “high” (window) and above “high”.

Operating Modes

1.

Limit switch: Relay 1 is controlled by the lower threshold („low“, relay 2 (if it exists) is controlled by the

upper threshold („high“). Both relays operate independently.

2.

Two position controller: The switching points are calibrated via the two thresholds „low“ and „high“

(hysteresis). Applications: e.g. for level control („low“ on, „high“: off).

3.
