Circuit diagram
• The LED lamps and relays connected to this module must
operate at currents lower than 30 V and 250 mA (When using
V IN with relay is 100 mV.). The module is equipped with a
built-in diode to absorb counter-electromotive force if a relay is
connected.

• The open collector output operates on wired OR logic, choos-
ing channels from CH1 to CH8 and connecting them to each
other. If an alarm is issued on one of the channels, an alarm
signal is issued.
