1.3 Modules
1.3.1 Slots of modules
AI-526/526P series instruments have five slots for modules to be installed (D dimension instruments have 3
slots: OUTP, AUX and COMM/AL1; D2 dimension instruments have 2 slots: OUTP and COMM/AUX). By
installing different modules, the controller can meet the requirements of different functions and output types.

Multiple function Input / Output (MIO):
Can input signal from 2-wire transmitter or 4-20mA signal by installing I4 (current input) module and I4 module
can provide 24VDC to transmitter. If a I2 (on-off signal input) module is installed, the instrument can switch
between set points SV1 and SV2 by an external switch. Cooperating with OUTP and installing a K3 module can
realize three-phase thyristor zero cross triggering output.

Main output (OUTP):
Commonly used as control output such as on-off control, standard PID control, and AI PID control. It can be
used as retransmission output of process value (PV) or set point (SV). Installing L1 or L4 modular can realize
relay contact output; installing X3 or X5 module can realize 0-20mA/4-20mA/0-10mA linear current output;
installing G module can realize SSR voltage output; installing W1 or W2 module can implement TRIAC no
contact switch output.
