Synapse
MQTT/Modbus TCP/8DI/8DO(R)/32x1-Wire/AC
Industrial digital input/output module for
remote process control and data acquisition
Thank you for choosing our product. The 7bit Synapse module designed as a remot e
Ethernet DIO, counter and 1-Wire temperature input module for industrial
automation and monitoring applications. MQTT connectivity option allows you to
create cloud-based monitoring & control applications. Built-in AC power supply and
2-port Ethernet switch simplify installation and cabling, extending network length and
allowing to install the module into existing network w/o extra equipment. The setup
is made easy with the web-config page.
Module Synapse is an OPEN-TYPE device. It should be installed in a control
cabinet free of airborne dust, humidity, electric shock and vibration
The device is operating at dangerous voltage rating. High voltage also may
occur at output terminals during it work. Please do not touch these
terminals when the device is powered on. DO NOT connect AC power to any
of input terminals, otherwise serious damage may occur. Please double
check all wiring before Synapse is getting powered up

3. Wiring
3.1 Ethernet
. Synapse has an embedded switch which make easy to connect numerous
modules simply, connecting them to each other in "daisy chain". As it is true Ethernet
witch, each connection may be up to 100 m. It is also possible to connect the devic e
at any breaking of existing Ethernet link.
3.2 Digital inputs
Use internal power supply for powering inputs via long cables with caution
due to low voltage and voltage drop you may have unstable DI signaling
3.3 Digital outputs
There are 2 groups by 4 outputs, each can be either relay or SSR
(by order) type. Due to Zero-cross detection unit, SSR provides comfort switching for
any AC load in the range 85 - 220V, 2A. Relay outputs is commonly used for dry
contacts and DC signals commutation.
To avoid sparks, limit switching currents and increase switching lifetime for
the outputs, it is strongly recommended to use extra snubber circuits for
inductive loads.
3.4 Safe power on
After power on the module can restore its outputs to a previous
state. For many applications it is convenient feature, but for some not. E.g. some parts
of a heavy machine may accidentally move on repower and cause dangerous situation.
To avoid this problem now there is a special setting to choose output state after
repower:

3.5 PWM for triac outputs
The duty cycle is set as 0 .. 100 which means how many
periods of AC current from one hundred will power the load. So the time base of the
PWM is 100 * 20 ms (1/50Hz) = 2 seconds. Before using DO for common ON
–

control set PWM values to 0.
