GPIO
General purpose interface for control integration with third party hardware. Offers 2x
inputs switching to ground, and 2x relay outputs on Phoenix connectors, in addition to
a +10V DC output.
Maximum current drawn from the +10V supply for all outputs combined must not
exceed 200mA
Output 1 can be wired as normally closed or normally open. Output 2 is normally
open.
For higher current or voltage applications, an external DC power supply may be used.
This also provides total isolation between the AHM processor and external equipment.
Maximum external supply voltage must not 24V DC. Maximum current
sink through any open collector output must not exceed 400mA.
Use the provided 10-pin Phoenix connector with strain relief for optimal cable
management.
6.
Control Network
RJ45 Gigabit Ethernet port. Connect a laptop, wireless router or switch to use with the
AHM System Manager, IP remote controllers, Custom Control app or TCP control. All
devices on the network must have compatible IP addresses.
To reset the network settings to factory default, see DIP switch settings in the I/O
Port paragraph above.

AHM-32 Processing Expansion Module
A processing expansion module can be fitted in the AHM-32 for applications like AEC (Acoustic Echo
for a list of available modules. Follow the fitting instructions of
the optional module for installation.
⚠
Installation of any optional module must only be carried out by technically
skilled personnel.
