DEM-5 Digital Expansion Module – 5 Channels
The DEM-5 provides five digital Inputs using a specific
resistor-to-resistor network connected to Universal Input.
The DEM-5 expander allows a single universal input (with
capability to measure resistance between 700 Ohm to
1600 Ohm) to monitor the status of up to five dry contacts.
Status Indicator
Built-in power and input LEDs indication and diagnostic purpose.
Relay Drive
External dry contact is driven by relay supports higher impendence load.
Jumpers
Built-in internal jumpers for easy diagnostic.
Ease of Installation
All I/Os are connected via field removable terminal block connectors for easy maintenance.
The controller casing fits standard DIN rail mounting.
