7bit Synapse Quick Manual

Synapse
Modbus TCP/8DI/8DO(R)/32x1-Wire/AC
Industrial digital input/output module for
remote process control and data acquisition
Quick guide
Thank you for choosing our product. The 7bit Synapse
module designed as a remote Ethernet DIO, counter and
1-Wire temperature input module for industrial automation
and monitoring applications. Built-in AC power supply and
2-port Ethernet switch simplifiy installation and cabling,
extending network length and allowing to install the module
into existing network w/o extra equipment.
1. Warning
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 occurs 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. Connection to device
Power the module on and connect to the Ethernet.
Module will get address automatically via DHCP. Find a new
device at DHCP table on your router and assign it a static IP.
Reboot device. All data and control will be accessible via
Modbus TCP, as shown in the table below.
4. Wiring
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 switch,
each connection may be up to 100 m. It is also possible to
connect the device at any breaking of existing Ethernet link.

Digital inputs. Synapse has 8 Digital Input ports with a
single common terminal. They may be powered by external 12
- 24V or internal isolated DC power supply, as sink or source
inputs. Each Input may be simultaneously used as a 32 bit
counter with maximum frequency 1KHz. To avoid jittering,
each input has adjustable filter (20 ms default, the shorter
impulse will not
(Refer to Modbus data table).

Digital outputs. Module Synapse has 8 Digital Outputs,
which are separated in two isolated groups. There are few
possible types of output circuits, such as triac (SSR) or relay
(R), or their combination (4+4). Due to Zero-cross detection
unit, SSR providing comfort switching any AC load in the range
85 - 220V, 2A. Relay outputs is commonly used for dry
contacts and DC signals commutation.
