Composition:
This EIO4 card is composed of the control interface with KX-TDA0190 and four external sensor interface and four external relay
control interface sections.
 1. Connection Diagram for External Sensor

Power to the external sensor is provided from the EIO4 card and must be grounded through the EIO4 card as indicated in the
diagram below. A pair of “sensor” and “common” lines are connected to the EIO4 card for each external sensor. The Hybrid IP-
PBX detects input from the sensor when the signal is under 100

Ω.

 2. External Relay control Section

This card has four external relay control interfaces.
