Remark
External 24 VDC
power source
Supplies power to the ALPHA2 and/or
Extension module.
Check to see if an external 24 VDC power source
is required for a specific ALPHA2 and an
Extension module.
Some sensors require additional parts.

* AI and AO cannot be used with the AC type ALPHA2.
(Note 1) I/O Extension Module /Analog Expansion Module
I/O Extension module
• EI: Digital input extension module of ALPHA2. 4 digital input ports can be added.
Type name: AL2-4EX-A2 (AC type) and AL2-4EX (DC type)
• EO: Digital output extension module of ALPHA2. 4 digital output ports can be added.
Type name: AL2-4EYR (AC type) and AL2-4EYT (DC type)
Analog Expansion module
• AO: Analog output extension module of ALPHA2. 2 analog output ports can be used.
Type name: AL2-2DA (DC type)
Only one of the above EI, EO, and AO can be used.
(Note 2) Analog signals that can be used for AI and AO of the DC type ALPHA2
• Analog Input (AI): 0-10V, PT100(*), thermocouple(*)
(*) To use a PT100 or thermocouple, a temperature sensor module is required separately.
Type name: AL2-2PT-ADP(Pt100 sensor), AL2-2TC-ADP(Thermocouple)
(Converts the Pt100/thermocouple to 0-10V)
• Analog Output (AO): 0-10V, 4-20mA
For details, refer to the ALPHA2 manuals (Installation Manual and Hardware Manual).
Requires a separate
100-240 VAC power source.
