12 TY-GC62-010A Rev.2● Terminals (9) and (10) are not used, but do not use them as relayterminals.■ 6.2 Internal FormatThe output format is a relay contact output as a comparator output, 4 to 20mA DC currentoutput as an analog output, or 1 to 5V DC voltage output. Analog output is an option.Current output or voltage output is set at the factory.(1) Analog output (4 to 20mA DC)This is exclusively for source only. Do not connect to the power supply (+).(2) Analog output (1 to 5V DC)■ 6.3 Contact ProtectionWhen driving an inductive load such as an auxiliary relay or solenoid valve with thecomparator output, make sure to insert the protection circuit for contact. A typical exampleof a protection circuit is shown below.Example of comparator output 1(For comparator output 2, read (1) to (2))Power (+)Power (-)GC62Comparator output 1Comparator output 24-20mA DCLoad: 400Ω max.Power (+)Power (-)GC62Comparator output 1Comparator output 2Load: 10kΩ min.1-5V DCGC62CRCRInductive load
