OrderableInline Surge Protection Device for Digital Sensors with A-Coded, Five-Pin M12 Connector
Overview
The ISP10 is a surge protection device for Modbus RTU sensors. The ISP10 provides protection that meets the IEC 61000-4-5, level 4 (4 kV, 2000 A) surge protection standard. It incorporates a T-junction that allows a sensor to be connected inline. The five-pin M12 connectors are configured to match the SunSentry system's trunk-line cable pinout, which is compatible with the RS485CBL 24 AWG RS-485 Cable with M12 Five-Pin Connector.
The ISP10 ties the sensor connector to earth ground via cable shielding. The trunk line cable shield passes through the T-junction untouched by the ISP10 and should be terminated separately at the main meteorological (met) enclosure.
Technical Description
The ISP10 uses a standard A-coded, five-pin M12 connector with shield termination via the coupling nut. The T-junction uses one plug M12 connector (for the incoming trunk line) and two socket M12 connectors (one for the continuing trunk line and one for the sensor port). Various pin adapters are available to change the pinouts of common sensors for compatibility with the ISP10 and the standard Campbell Scientific pinout.
One ISP10 can be connected directly to another ISP10 side by side without cabling when sensors are close to one another. Alternatively, the RS485CBL-Xm-M can be used to daisy-chain one sensor or ISP10 to another.
A hole in the middle of the ISP10 is used for grounding and mounting with the included #10 screw. Mount the ISP10 to an earth-grounded, conductive part for proper surge protection.
The ISP10 is shipped with the following items:
- #17 high-speed steel drill bit for pilot hole required for the self-tapping screw
- Self-tapping screw (#10-32 x 1 410SS hex washer head thread cutting screw)
- 5 cc packet protective oxide-inhibitor grease

Protective M12 Socket Connector Cap
The 43656 is a protective cap to cover an unused M12 socket connector. It is commonly used to protect the unused output side of the SunSentry system's daisy-chain trunk-line tee.
OrderableRS485CBL
Five-Conductor Cable with M12 Five-Pin A-Coded Connector
The RS485CBL cable uses a five-conductor shielded cable with an M12 five-pin A-coded connector. The cable has a UV-resistant, polyurethane jacket. The RS485CBL has been custom designed for sensors that use the RS-485 Modbus protocol with integrated power and signal lines. The signal lines have twisted pairs with 24-gauge conductors, and the power lines have a heavier 20-gauge wire, making the cable uniquely suitable for sensors with a higher current draw that have either short or long runs. An aluminum Mylar shield is grounded via a drain wire and connected to the M12 nut.

The 44732 is an accessory adapter cable designed so you can connect a Lufft all-in-one sensor that has an eight-pin M12 connector to the RS485CBL 24 AWG RS-485 Cable with M12 Five-Pin Connector through a five-pin M12 connection. This adapter cable provides a simple, factory-built interface to integrate compatible Lufft sensors with SunSentry systems. The 44732 features overmolded M12 connectors with a printed identification label.

RS485CBL Adapter for SunSentry Used with Digital EKO Pyranometer
The 44338 adapter enables a single trunk-line cable to connect an array-mounted digital EKO pyranometer to the SunSentry Solar Operational Meteorological Monitoring Station. The adapter remaps the pin assignments between the two interfaces so the pyranometer is fully compatible with the RS485CBL 24 AWG RS-485 Cable with M12 Five-Pin Connector in a daisy chain with other sensors. The 44338 routes the cable shield through the connector's coupling nut, improving surge protection and reducing signal noise for more reliable operation.

RS485CBL Adapter for SunSentry Used with Atonometrics Sensor (RC22 PV Reference Cell)
The 44339 adapter enables you to integrate an Atonometrics sensor—such as the RC22 PV Reference Cell—into a daisy-chain configuration on a SunSentry Solar Operational Meteorological Monitoring Station. The adapter allows the sensor to connect to the SunSentry system using a single trunk-line cable by remapping the pin assignments to match the RS485CBL 24 AWG RS-485 Cable with M12 Five-Pin Connector. The 44339 also routes the cable shield through the connector's coupling nut, improving surge protection and reducing signal noise for more reliable operation.

RS485CBL Adapter for SunSentry Used with CS241DM G2 Temperature Sensor
The 44340 adapter allows a CS241DM G2 temperature sensor to be a direct replacement for the CS241DM temperature sensor. The pin assignments changed in the CS241DM G2 version, so the 44340 adapter converts the new pin assignment to the older version pin assignment, enabling the CS241DM G2 to use the same cable as the CS241DM.
