INSTALLATION

0-10

Vdc

–

1. Use shielded, twisted cable (1) 61m (200 ft) max.

2. Cut and tape back shield wire (2) at sensor (3) end.

3. Connect the other end of shield wire to ground (4) (for example, use a stud in an enclosure).

4-20 mA UI Wiring

The inputs support self-powered 4–20 mA sensors. Input accuracy is ±2% of span, without user calibration. Use a 499 ohm resistor

wired across the input terminals.

NOTE: When using an externally powered 4–20 mA sensor, be sure to de-energize its power supply before making or

changing any wiring connections to the MS-E10 Controller.

This is in addition to removing power from the MS-E10 Controller.

resistor in place. Otherwise, even a momentary application of power (for example, 24 Vdc) to the UI terminals without the resistor may damage

circuitry on the MS-E10 Controller. Only after completing all input wiring should you restore power to such external power supplies.

4. De-energize the 4-20 mA sensor (3) and remove any power from the MS-E10. See Note, above.

5. Use shielded, twisted cable (1) 61m (200 ft) max.

6. Cut and tape back shield wire (2) at sensor (3) end.

7. Connect the other end of shield wire to ground (4) (for example, use a stud in an enclosure).

8. Wire the supplied 499 Ohm resistor (5) across input terminals. See Note, above.

Binary Input UI Wiring

The universal inputs support normal dry (equipment status) contacts. Standard dry contacts must have a 1 Hz (or less) COS frequency,

with minimum dwell time > 500 ms (contacts must remain open at least 500 ms and be closed at least 500 ms). Dry contacts support 11

Vdc open circuits or 733 µA short-circuit current.

0V U5 U4 0V U3 U2 0V U1

0 V U 5 U 4 0 V U 3 U 2 0 V U 1

Due to our policy of continuous product innovation, some specifications may change without notification.

DO NOT apply external power to the UI inputs without the 499 ohm
