Contact rated capacity:
(250VAC/1A or 30VDC/1A)
Contact using description:(refer to
8-02, 8-03)
Analog frequency signal input terminal or multifunction input terminals S7 (H level:>8V, L level:<2V,
PNP only) (refer to5-06 description)
Common contact for S1~S5 (S6, S7) in PNP (Source) input. Shift to PNP position (refer to wiring
diagram) of SW1 when used PNP input
1. Common contact and analog input /output signal for S1~S5 in NPN (Sink) input.
Shift to NPN position (refer to wiring diagram I) of SW1 when used NPN input.
2. AGND for AIN,AI2 and FM+ (analog input /output signal) & 24G for S1~S6 (digital input /output
signal in NPN (Sink) input). Shift to NPN position (refer to wiring diagram II) of SW1 when used
NPN input.
The positive analog output for multifunction (refer to 8-00 description), the signal for output terminal is
0-10VDC (below 2mA).
