5. Wiring. See Figure 3 for Digital Speed Reference (DI-08) connections. Connect digital input signals to
terminals TC1-TC10 (+) and TC11 (-). See Table 2 for terminal functions.
CAUTION
KEEP DIGITAL SIGNAL (I.E. CONTROL CIRCUIT) WIRING
SEPARATE FROM MAIN CIRCUIT INPUT/OUTPUT WIRING.
CAUTION
TO PREVENT ERRONEOUS OPERATION CAUSED BY NOISE
INTERFERENCE, USE SHEILDED CABLE FOR DIGITAL SIGNAL
WIRING, AND LIMIT DISTANCE TO 10M (33 FEET) OR LESS.
IMPORTANT
The DI-08 input circuits can receive output of relay contacts or transistor (open
collector).
– Use relays with highly reliable contacts (for very small current) with a
capacity of 30VDC or more and rated current of 100mA or higher.
– Use transistor (open collector) with rated voltage of 35VDC or more and
rated current of 30mA or higher.
