I/O Module OB-215 was designed to collect information from various sensors and transmit this data via MODBUS protocol.

Additionally OB-215 provides threshold load control. The device integrates perfectly with the EM series of controllers.

OB-215 supports the following types of sensors:

• sensors with voltage output (0 – 10V)
• sensors with DC output (0 – 20mA)
• temperature sensors of various types
• water, gas, electricity counters can be connected via pulse input
• all kinds of Arduino sensors
• “dry contact” sensors with open collectors
• 1-Wire, I2C sensors

OB-215 is able to operate as:

• a temperature controller for cooling and heating units
• a “pulse relay” with adjustable pulse frequency
• a protocol converter for refrigerating controllers – UART (TTL) into MODBUS (RS-485)
• an equipment control unit with relay output with a breaking capacity up to 5A

Also the device can monitor the status (closed / open) of security sensors, alarm systems, auxiliary contacts of circuit breakers, machine operations.

OB-215 can perform such logical operations as:

• load management according to the thresholds provided
• pulse counter
