Terminal Block - TB3 (A Quad B Board)
Figure 5.1 provides interconnect information between the position
controller and TB3 on the A Quad B Board.
ATTENTION: To guard against possible damage to the A
!
Quad B Board, assure that wiring between TB3 and the position
controller is correct. Refer to Figure 5.1.

Recommended Wire – Belden #9728 or equivalent. Maximum distance between the A Quad B Board and
the position controller is 40 feet (12.2 meters) using a 5 volt signal. For distances up to 300 feet (91 meters),
2
18 AWG (0.8 mm
) wire (Belden 9388 or equivalent) and an 8 to 15V DC power supply must be used.

For proper operation when interconnecting to IMC classic products (IMC 110, 12x), the B and B (NOT)
signals must be reversed.
3
When interfacing to IMC 121 or 123 controllers, use the 1391-CAQB cable. When interfacing to the
integrated packages of the MAX or S Class controls, use the 1391-SAQB or 1391 SAQBK cable.
The A Quad B option operates in the same manner as the Allen-Bradley
845H Line Driver Encoder (26LS31 line driver output). The option
requires either a regulated +5V DC at terminal 7 or an unregulated +8 to
+15V DC input at terminal 9 (board draws 125mA maximum). The pulse
train output is selectable to 256, 512, 1024 or 2048 lines per revolution via
the Encoder Output switch, S1 (see page 5-6).
Terminal Block - TB4
Please note that there are no connections to TB4-20 & 22.
Contactor Coil (TB4, Terminals 11, 12)
Connections to the coil of the integral contactor are performed at these
terminals. The coil voltage is 115V AC, 50/60 Hz.
Important: Drives with a catalog number of 1391-DESxx-DI-AQB-A will
have a 24V DC coil. Drives with a catalog number of 1391-DESxx-DI-
AQB-B will have a 240V AC coil.
