INTRODUCTION
Overview
In many installations, having cost-eective, robust, and simple hardware becomes a key factor in
winning a project. The Core range provides the perfect solution to meet these criteria. Innon have
collaborated with Atimus, a company with a wealth of experience in the eld, and are proud to
present Core IO!
The 40 MULTI is a 40 point I/O device providing a perfect balance of analogue and digital inputs
and outputs. The device supports a variety of sensor types, allows the use of pulse counters and
integrates a watchdog to safely position its outputs in case of a network failure.
BEMS communication is based on the robust and well-proven Modbus RTU over RS485 or Modbus
TCP (IP model only).
The conguration of the device can be achieved through the network using either the web interface
(IP version only) or Modbus conguration registers or by using an Android device and connecting
over Bluetooth using the dedicated app.

HARDWARE
Overview
The CR-IO-40MULTI-RS only comes with the RS485 port, while the CR-IO-40MULTI-IP comes with
both RS485 and IP ports.
Both models come with Bluetooth on-board, so conguration can be achieved using an Android
device and the dedicated app. The IP CR-IO-40MULTI-IP model also integrates a web server
conguration interface, accessible via a PC web browser.
Wiring Power Supply
AC (24Vac) DC (24Vdc)
This Core IO model
The CR-IO-40MULTI-RS and the CR-IO-40MULTI-IP modules come with 8 universal inputs, 8 universal
outputs, 16 digital inputs and 8 relay outputs.

Please note - both IP and RS versions can use the RS485 port to respond to serial Modbus master
comms from the BEMS, but neither version can use the RS485 port to act as a Modbus master
or gateway.

Front LED Panel
The LEDs in the front panel can be used to get direct feedback on the status of the I/Os of Core IO
and more general information.
Below are some tables that will help decode each LED behaviour –

Digital Inputs
Digital Inputs can have a clean/volt free contact connected to Core IO to read its open/closed status.
Each digital input can be congured to be either:
• Digital Input direct
• Digital Input reverse
• Pulse input
While the “direct” and “reverse” mode would basically return status “False (0)” or “True (1)” when
the contact is either open or closed, the third mode “pulse input” is used to return a counter value
increasing by 1 unit every time the digital input closes.
A dedicated chapter on the pulse input topic is available later in this manual.
The pulse input can count eectively up to a frequency of 100Hz, with 50% duty cycle.
Digital Outputs (Relay)
The Digital Outputs are driven by relays.
Each Digital Output can be congured to be either:
• Digital Output direct
• Digital Output reverse (eectively reversing the logic of the output status)
For every Digital Output it is possible to congure the desired status when the “Watchdog”
function is triggered (BEMS oine for over a timeout delay).

Universal Inputs
Universal Inputs are used to connect analogue signal inputs to Core IO.
A variety of sensors and signals can be connected to a Universal Input. In terms of active signals,
both voltage (0-10V, 2-10V) and current (0-20mA, 4-20mA) are supported directly. As for passive
sensors, a long list of dierent thermistor types is available, on top of the direct resistance reading
(in case you prefer to run the conversion to temperature in the BEMS strategy for dedicated types
of sensors)
Here is a list of the supported input types for each individual Universal Input:
• Analogue Input 0-10V
• Analogue Input 2-10V
• Analogue Input 0-20 mA
• Analogue Input 4-20 mA
• PT1000
• NI1000 DIN
• NI1000 LG
• NTC1K8
• NTC2K2
• NTC3K3
• NTC10K3A1
• NTC10K4A1
• NTC10KCAREL
• NTC20K6A1
• Resistor Value
