Users manual
1. Short description
TCW120B is a multifunctional device for remote monitoring and management. It is an
Ethernet based controller, which is designed to work in IP-based networks and managed by
WEB interface or SNMP programs. Its I/O interface - relay outputs, analog and digital inputs,
is suitable for solving specific problems in various fields such as remote control, alarm
systems, industrial process automation, control and management of computer networks etc.
High precision digital temperature sensor is option.
2. Features
• 10 Mbit Ethernet connectivity
• Password protected web based configuration and control
• 2 digital inputs, 2 analog inputs, 1 temperature sensor input
• Two 3A/24V relay outputs
• SNMP v.1, SMTP, ICMP, VLAN support
• Sending SNMP Traps messages under certain conditions
• Sending E-mail messages under certain conditions
• Relay restart on ping/echo timeout
• TCW120B can be used as standalone device or as a part of monitoring and
management system
• MAC Address filtering
• Remote FTP firmware update

6. Example Applications 6.1 Remote control The controlled device is connected in series with the relay contacts. Users can operate TCW120B using a web browser or by using custom SNMP applications. Both relay outputs are managed independently of each other. - Page 4 A relay output from the monitored device is connected to one of the digital inputs of TCW120B. When an event occurs – the controller sends an E-mail message to a predefined e-mail address. SNMP Trap message is sent if custom SNMP monitoring software is used.

3. Connect the I/O pins of the controller according to the required application. 4. Connect the power supply. If the red LED is blinking, it indicates that the power supply is OK. By default TCW120B comes with the following network settings: IP:192.168.1.2 , Subnet Mask: 255.255.255.0 , Default Gateway: 192.168.1.1... - Page 6 The controller supports only one active session – only one user (administrator) can operate the device. If another user tries to login, the following message appears: “Someone’s logged in” The active session will be terminated automatically, if the current user stays inactive for 2 minutes.
- Page 7 5 seconds as the maximum number of consecutive restarts is limited to 5. One of the possibilities of TCW120B is to send e-mail messages when the status of digital inputs Digital Input 1 and Digital Input 2 is changed. To do this, the following parameters must be set: •...
- Page 8 • Host Name • MAC – device MAC address If multiply TCW120B controllers are used on the same network, please change the IP address after connecting the device to the network. This will avoid devices installed on the network with the same factory default IP address at the same time.
- Page 9 • Mailserver IP – IP address of SMTP mail server • E-mail – sender e-mail 8.6 SNMP Setup page TCW120B supports SNMP v.1 that enables trap delivery to an SNMP management application. This enables the device to be part of large monitoring and control networks. The possible settings are: •...
- Page 10 SNMP trap messages are sent for the following conditions: when event occurs on Digital Input 1 or Digital Input 2 (the signal changes its state) measured voltage on Analog Input 1 и Analog Input 2 is outside the predefined range measured temperature Is outside the predefined range restart Setting range for sending SNMP trap messages is done only through SNMP.
