Field Wiring Arm
Cat. No. 1771ĆWH
Do not exceed the specified isolation voltage when using multiple power sources.
7. Connect TTL output devices using Belden 8761 shielded cable as
shown in the connection diagram. Do not exceed 50 cable feet for
any output device. Connect the insulated wires to their respective
terminals on the field wiring arm.
Driving Inputs with Outputs
Input terminals of the TTL input module (cat. no. 1771-IGD) may be
directly driven by the outputs of a TTL output module (cat. no.
1771-OGD). Connect the cable shield between modules at one end
only.
