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

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

The following abbreviations are used for Modbus registers functions: C -

Coils, DI - Digital Inputs, HR/IR – Holding/Input Registers, and their data

format: W - Word (2 bytes), DW - Double Word, b – bit. R/W – Read/Wri t e

mode.

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.

AC, 85 - 220V 2A, Zero-crossing switching.

Max. frequency: 100 Hz

3.2 Digital inputs

Address

Description

DI0 ~ DI7

Digital Inputs

HR20 ~ HR27

Input filters (0 - disabled)

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.

Description

C0 ~ C7

Digital outputs

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:

Address

Description

HR35

Safety state 0 – off, 1 - on

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 – OFF

control set PWM values to 0.
