and V, etc. N means no module been installed.

④

Shows the module type of main output (OUTP). Selectable modules are L1, L2, L4, W1,

W2, G, K1, K3, K5, K6, X3, X5 etc.

⑤

Shows the module type of alarm (ALM). Selectable modules are L0, L2, L3,L4, W1, W2, G,

etc.

⑥

Shows the module type of auxiliary output (AUX). Selectable modules are L0, L2, L3, L4,

W1, W2, G, K1, X3,X5, etc.

⑦

Shows the module type of communication (COMM). Selectable modules are S, S4, V, etc.

⑧

Shows the power supply of the instrument. If left blank, the power of the instrument is

100~240VAC. Added "24VDC" means the power supply of 20~32V DC or AC power

⑨

Shows the optional extended graduation spec (If none, leave it blank). AI-516 series

instruments support many input types including popular thermocouples, RTDs, linear

voltage, current and resistance inputs. If needed, an additional specification not mentioned

in input type selection (InP) table can be extended.

Note 1: The instrument applies the technology of automatic zero and digital calibration, and is free

of maintenance. If the error exceeds certain range, generally, cleaning and drying the inside of the

instrument can fix it. If not, send the instrument back to the factory to examine and repair.

1.3 Modules

1.3.1 Slots of modules

AI-516/516P series instruments have five slots for modules to be installed (D dimension

instruments have 3slots: OUTP, AUX and COMM/AL1; D2/D6 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;
