Interface Methods

The isolated logic inputs may be interfaced to the user’s control system in a

variety of ways. In all cases the inputs are normally in a logic HIGH state when

left floating. For purposes of this manual we will show three interface methods:

1] Switch Interface.

2] Open Collector Interface.

3] TTL Interface.

We will also show IM483 inputs connected to the IMS LYNX modular motion

controller, which is a powerful machine control soulution.

Switch Interface

A switch connected between the input and the opto supply ground will sink the

input. If this method is used a SPST (Single-Pole, Single-Throw) switch works

well for enable and direction. A normally-open momentary switch works well

for reset. Figure 7.6 illustrates a SPST switch connected to the direction input.
