Introduction
Overview
OptoIso 3/4 adapter is a device that opt-isolates Mk3/4 controller inputs from
external devices such as limit switches, proximity sensors, input switches,
probes and similar devices.
Its main function is to protect the input circuitry of Mk3/4 controller from
any damage that may occur due to improper wiring or power surges at the side
of externally connected device. Also, using this adapter reduces electrical
noise influence at controller inputs and makes up for easy connection of
proximity switches.
Features and specifications
- Single adapter offers 4 opt-isolated input channels
- Allows connection for up to 4 limit switches, push-buttons, probes, PNP proximity sensors and similar devices
- Each input corresponds to its dedicated open collector output
- Max voltage value of input signal is 24VDC
- It can be used as a simple voltage level translator where you need to connect devices that function at different voltage levels (5V, 12V, 24V)
- Adapter was designed specifically for Mk3/4 controller but it can be used with any other board that needs opt-isolated inputs.
