Compact 16-point 24V dc Sink/Source High-speed Input Module

DIN Rail Mounting

The module can be mounted using the following DIN rails: 35 x 7.5 mm (EN 50 022

- 35 x 7.5) or 35 x 15 mm (EN 50 022 - 35 x 15).

Before mounting the module on a DIN rail, close the DIN rail latches. Press the DIN

rail mounting area of the module against the DIN rail. The latches will momentarily

open and lock into place.

Replacing a Single Module within a System

The module can be replaced while the system is mounted to a panel (or DIN rail).

1. Remove power. See important note on page 4.

2. On the module to be removed, remove the upper and lower mounting

screws from the module (or open the DIN latches using a flat-blade or

phillips style screw driver).

3. Move the bus lever to the right to disconnect (unlock) the bus.

4. On the right-side adjacent module, move its bus lever to the right (unlock)

to disconnect it from the module to be removed.

5. Gently slide the disconnected module forward. If you feel excessive

resistance, check that the module has been disconnected from the bus, and

that both mounting screws have been removed (or DIN latches opened).

TIP

6. Before installing the replacement module, be sure that the bus lever on the

module to be installed, and on the right-side adjacent module are in the

unlocked (fully right) position.

7. Slide the replacement module into the open slot.

8. Connect the modules together by locking (fully left) the bus levers on the

replacement module and the right-side adjacent module.

9. Replace the mounting screws (or snap the module onto the DIN rail).

It may be necessary to rock the module slightly from front

to back to remove it, or, in a panel-mounted system, to

loosen the screws of adjacent modules.
