Digital Input Option Card
DI-16H2
Installation and Wiring:
1. Disconnect all electrical power to the drive.
2. Remove the drive’s front cover.
3. Check that the “CHARGE” indicator lamp inside the drive is off.
4. Use a voltmeter to verify that the voltage at the incoming power terminals (L1, L2, L3) has been disconnected.
5. Option Card Installation: See Figure 1. Position the option card above the control board’s 2CN connector and gently
press the card into place.
6. Wiring: Refer to Figures 2 and 3 and Tables 2 & 3. Make wire connections between the DI-16H2 card and drive as well
as all peripheral devices. Observe the following:
a) Connect digital input signals to Terminal Blocks TC1 and TC2.
b) Keep the DI-16H2 (i.e. control circuit) wiring separate from main circuit input/output wiring. A separate metallic
grounded conduit with only the option card’s wiring running through it is preferred.
c) To prevent erroneous operation caused by noise interference, use shielded cable for control signal
wiring. Limit the distance to 50m (164 feet) or less.
d) Route wires from the drive and connect to the peripheral device. Refer to the drive technical manual for further
information on the use of shielded cable.
e) Connect the green grounding lead wire (E) from the DI-16H2 card to the grounding terminal TB3 (12 for G5) on
the drive’s control board.
Important: The DI-16H2 input circuits can receive the output of relay contacts and transistors (open collector).
a) Use relays with highly reliable contacts (for very small current) with a rated voltage of 30VDC or more and a
rated current of 100mA or higher.
b) Use transistors (open collector) with a rated voltage of 35VDC or more and a rated current of 30mA or
higher.
7. Adjustment: Switch S1 (12 or 16 bit selection) must be set properly. See Tables 1 and 3. The drive will have to be
programmed for the input requirements of the peripheral device. See Table 4 and Figure 2.
Important: For the digital reference to function properly, the drive needs to be programmed to use the digital
reference. This can be done in one of two ways:
a) If drive always uses the DI-08 speed reference:
Program b1-01 = “3” (Option PCB)
b) If the drive is using multi-function digital inputs to select multiple speed references:
1. Program b1-01 = “0”, “1”, or “2” (depends on required speed reference source).
2. H1-03 (or other input) = “2” (Option / Inverter Select).
3. Close terminal S5 (5 on the G5) on the drive’s control board to select the DI-08 digital reference.
8. Reinstall and secure the drive’s front cover.
9. Place this instruction sheet with the drive’s technical manual.
