Connector TELTONIKA TRB245 TRB255 8-pin 8A PR4IO17K for serial and I/O connections

Connector designed for TELTONIKA TRB245 and TRB255 devices, providing an 8-pin interface for serial and I/O connections. Rated for up to 8 A, this compact connector ensures secure wiring of sensors, actuators and communication lines in industrial and telematics installations. The connector’s form factor matches the input/output pinout of compatible TELTONIKA routers, enabling straightforward replacement or field wiring without additional adaptors.

Advantages

The connector delivers reliable electrical contact for serial ports and digital/analog I/O channels while supporting currents up to 8 A. Its compact design reduces panel space requirements and facilitates neat cable routing. Durable contacts and a stable housing help maintain consistent connections in environments with vibration or moderate mechanical stress. The connector is compatible with common cable sizes used in sensor and actuator wiring, enabling straightforward installation and maintenance.

Suitable for

• Wiring serial communication lines (RS232/RS485) to compatible routers
• Connecting digital and analog I/O signals from sensors and actuators
• Industrial telematics installations and vehicle-mounted systems
• Field replacement of damaged or worn I/O connectors

Key specifications

• Pin count: 8 pins for combined serial and I/O connections
• Current rating: 8 A per connector
• Compatibility: form factor matching specific TELTONIKA router I/O ports
• Mounting type: removable/pluggable inline connector for device terminals
• Material: durable contact and housing materials designed for electrical and mechanical reliability
• Suitable cable gauge: compatible with common sensor and actuator wiring sizes

How to use

Identify the I/O terminal on the router and align the connector so that pin orientation matches the device pinout. Insert the connector firmly into the device terminal until it seats and secures. Route and secure cables to prevent strain on the connector. For serial connections, ensure proper TX/RX and ground wiring; for I/O signals, observe correct polarity and shielding where required. Verify connections with a multimeter or the router’s diagnostic tools before powering the system.

Recommendations

Use appropriately rated wiring and secure cable strain relief to maintain reliable connections. Avoid exceeding the 8 A rating and keep the connector free from corrosive substances. For installations exposed to moisture or heavy contamination, use additional sealing or protective enclosures to prolong service life.
