Use terminal A2 to input a voltage or a current signal. Set the signal type as shown in Table 1. Figure 1. Location of DIP Switch S1 Table 1. MFAI Terminal A2 Signal Settings Terminal Input Signal DIP Switch Settings Parameter Switch Setting No. Signal Level A2 Current input S1 I (Default) H3-09 2: 4 mA to 20 mA/0% to 100% (input impedance: 250 Ω) 3: 0 mA to 20 mA/0% to 100% (input impedance: 250 Ω) Voltage input V 0: 0 V to 10 V/0% to 100% (with zero limit) (input impedance: 20 kΩ) 1: 0 V to 10 V/0% to 100% (without zero limit) (input impedance: 20 kΩ) Note: Use tweezers or a jig with a tip width of approximately 0.8 mm (0.03 in) to set DIP switches.
