The I/O module OB-215 designed to collect data from various sensors and transmit this information via the MODBUS protocol.
In addition, OB-215 provides the possibility of threshold load management.

Perfectly integrates with EM series controllers.

To OB-215 can be connected:

• Sensors with voltage output (0 - 10 V)
• Sensors with DC output (0 - 20 mA).
• Temperature sensors of various modifications.
• Water, gas, electricity meter via pulse input.
• Arduino integrated sensors.
• Sensors with open collector of "dry contact" type.
• 1-Wire sensors, I2C.

OB-215 can work as:

• Temperature controller for refrigeration and thermal installations.
• "Pulse relay" with adjustable pulse frequency.
• Protocol converter for refrigeration controllers - UART (TTL) to MODBUS (RS-485).
• Equipment control unit via relay output with switching power up to 5A.

Also, the device can track the state (closed/open) for security sensors, alarms, additional contacts of the switch position, machine operation.

OB-215 can work logically:

• Ioad control by specified thresholds.
• Pulse counter.
• The RS-485 interface provides the interaction of the device with other PLCs (programmable logic controller) of free logic via the MODBUS protocol.
• When you complete the device with PLC from Novatek-Electro YeM-481/486 will be active convenient configuration interface through the cloud server Overvis.
