7bit Synapse (v1)

Multifunctional distributed peripheral module

A multifunctional distributed peripheral module for monitoring and control systems that supports communications via industrial Modbus TCP and MQTT protocols. The presence of 2 Ethernet ports and ~220V power supply simplifies installation into the existing infrastructure as much as possible, and the slim body allows it to be placed in typical electrical distribution cabinets.  The module has discrete I/O (8 / 8) and a 1Wire digital bus for connecting up to 32 sensors.

Support for the MQTT protocol allows the module to be used in cloud-based monitoring and control systems.

Applications
  • Building management, HVAC, heating stations
  • Monitoring of production lines and machines
  • Greenhouses
  • Various monitoring and automation systems
Overview of the features

The module has 8 digital inputs (also with a counter function) for monitoring the equipment status and 8 relays for control.

Digital inputs

  • 8 bidirectional inputs with 24V level and one common point
  • The module has its own 24V power supply to power the inputs
  • Built-in digital filter
  • Each input can be used as a counter (max. frequency 1 kHz).

Digital outputs

  • 8 outputs, 2 relay groups
  • Max. load 5А
  • Counter function for each output

Sensors with a 1Wire interface are currently the most cost-effective solution for measuring temperatures in the climatic range (-40 + 85°).  It should be noted that sensors of this type are quite sensitive to electromagnetic interference on the communication line, but the Synapse module uses a specialized line driver configured for the worst-case scenario when many sensors are connected or a long cable is used.

Features of the 1Wire interface of the 7bit Synapse module
  • 3-wire “active” power supply circuit for sensors (5V), with short-circuit protection
  • Maximum number of sensors – 32
  • The maximum length of the communication cable is 200 meters.
  • Ability to restart the driver
  • Automatically searches for sensors by hardware addresses and stores their order in non-volatile memory

In production monitoring systems, it is often necessary to assess not only the condition of equipment, such as machine tools, but also their productivity, resource and material consumption, which is easiest to do with a simple speed sensor or proximity sensor and counting pulses from it.  Another task is to assess the alignment of mechanisms for timely preventive maintenance or repair. Our module has everything you need to do this, as each discrete channel has such functions.

Counting functions
  • Counting the number
  • Calculating the duration of staying in the state
  • The counters are 32-bit, and the values are stored in the device’s non-volatile memory.
  • Digital filters at the inputs ensure error-free counting
  • The maximum pulse frequency is 1 kHz.

Connecting an Ethernet device to the network requires a free slot in a router, switch, or second adapter in your computer.  If there are no free ports at the installation site, you will need to configure additional equipment. But not in the case of the Synapse module, because it has a 2-port switch on board that works in “bridge” mode, so the module can be installed almost anywhere in the existing infrastructure.

  • Two Ethernet ports
  • Port operation mode: “bridge”
  • The cable length on any port is 100 meters.
  • The speed is 100 Mbps.

Thanks to the IoT (Internet of Things) support of the MQTT protocol, the module can be directly integrated into smart city applications or be self-sufficient to create a simple monitoring system for an object such as a heating station. The event-oriented MQTT protocol allows data to be transmitted over slow GPRS networks. The necessary visualization and interface of the controlled object can be created in a cloud-based system such as Level2.
