Solid-State Relay Module PLC-OPT- 5DC/ 5DC/100KHZ-G
Product Description
The PLC-OPT- 5DC/ 5DC/100KHZ-G is designed as an input solid-state relay with a DC voltage output, facilitating a push-pull operation. It operates at a transmission frequency of 100 kHz, providing reliable performance across various applications.
Input specifications include a nominal voltage of 5 V DC, with a permissible input voltage range between 2.5 V DC and 6 V DC. The device exhibits a typical input current of 8 mA and a rapid response time of 1 µs, ensuring efficient signal processing. The output capabilities range from 4 V DC to 18 V DC with a limiting continuous current of 50 mA, and it utilizes a 3-conductor push-pull output circuit.
Integrated features include a yellow LED for operational voltage indication and protective circuitry for reverse polarity and surge voltage protection exceeding 35 V. The module is constructed to meet basic insulation standards with an overvoltage category of II and a pollution degree of 2, ensuring its suitability for demanding environments.
With a compact design measuring 6.2 mm in width, 80 mm in height, and 94 mm in depth, the relay module is suitable for DIN rail mounting and can be installed in any orientation. It operates effectively in ambient temperatures ranging from -20 °C to 60 °C and is rated IP20 for protection.
