4-7 Connecting Inputs (analog inputs)
■ Connecting input 1
Multiple input 1 supports various sensor inputs. Connect as follows according to the
sensor being used.
• Thermocouple input • RTD input
• dc voltage input • dc current input
• Applying voltage across dc current input terminals (31) and (33) may cause
faulty operation.
• Take care of polarities (+,-) when wiring inputs.
• Use only shielded cable for wiring inputs.
• When using a thermocouple input, prevent air blasts from coming into contact
with the terminal. Doing so might cause a reading error.
