Overview The EXP-AIN expansion board enables monitoring and controlling of industrial processes using 8 industrial analog sensor channels.The channels support voltage-based ( ±10V), current-based (±20mA) or resistive sensors . Zerynth expansion boards work seamlessly with all of the Zerynth Development boards. Combined, they can act as a Development Board for prototyping a Product, and a core for industrial applications. Modular Expansion System Zerynth Development boards offer a game-changing way of connecting and adding functionalities to your application in a simple and easy way. The...

General Characteristics 8 Analog Channels: Each channel can be configured as ○ 4-20 mA Current channel (full input range +/-20mA) 0-10V Voltage channel (full input range +/-10V) Resistive Sensor Channel: Internal bias is designed for NTC thermistor probes rated 10kΩ @ 25°C (with B=3435), but other probes may also be used depending on the temperature range to be measured. Current Clamp channel based on voltage or current signal( within channel Voltage and current ratings).

Isolated Ground reference for analog bias NOTE: All I/O pins on screw terminals are isolated from the zBUS interface. ● Overvoltage Cat.II / Pollution Deg.II NOTE: Analog channel to channel isolation > 250kΩ Technical Specifications Environmental Conditions Temperature Storage Temperature Degree Protection Dip-Switches Rotary Switch SW1 : Chooses the address of the ADC Chip. Enable multiple boards to be connected simultaneously. Position Rotary Switch SW2 : Controls which hardware channel you want to link the interrupt. Position

S1 Switch : Each Analog channel can be configured with 3 DIP switches that enable specific features, The same settings are applied for S2, S3, S4. PIN AINx read as voltage AINx read as Current AINx read as resistive sensor AINy read as voltage AINy read as Current AINy read as resistive sensor Each Switch controls two ADC channels as follows ● For Voltage measurement - 0 10V standard industrial voltage sensor (Select switch number n according to the needed analog channel): Switch pin For Current measurement - 4-20 mA standard industrial sensor: Switch pin

NOTE: Current clamp (transformer) can be connected using the 4-20mA configuration of the DIP switches, exploiting the full input range of ±20mA. That is ±2V across the on-board 100 Ohm resistor, which cannot handle power dissipation required by ±10V. Current transformer turns ratio must be chosen so that the secondary current does not exceed 20mA. NOTE: All input/Output pins on this board have a max voltage rating of 36V across positive/negative pairs. Power Supply: The board is powered by the 5V internal signal from the ZM1 Development board. zBUS Pin Description PIN-Name
