The RL-5900 is an integrated power supply and isolation relay designed to provide high current switching capacity for flow, pressure, level or temperature primary switching devices such as reed contacts and transistors. The RL-5900 series takes 110 VAC or 230 VAC power in and provides a 24 VDC power supply for sensor excitation. The RL-5900 series also has an integrated isolation relay rated at 10 amps at 240 VAC. All of these features, combined into a single compact package, make the RL-5900 series an excellent standalone solution for sensor excitation and contact protection.
