AC Power Input
Terminals 1 and 2 are for power. Terminal 9 is the earth ground.
Use a 0.5 Amp, 250 V, fast-acting fuse in line with your AC power connection.
Process Variable Input
The 535 accommodates the following types of process variable inputs:
• Thermocouple Input
• RTD Input
• Voltage Input
• Milliamp Input with External Power Supply
• Milliamp Input with Internal Power Supply
Each type of input can be wired for PV1 (terminals 31 and 32) or for PV2 (ter-
minals 28 and 29).
