Option L6/L6E – 115V AC Interface Board Requirements
Circuits used with Option L6/L6E must be capable of operating with
high = true logic. In the low state, circuits must generate a voltage of
no more than 30V AC. Leakage current must be less than 10 mA into
a 6.5k ohm load. In the high state, circuits must generate a voltage of
90-115V AC ±10% and source a current of approximately 20 mA for
each input. The L6/L6E option is compatible with these
Allen-Bradley PLC modules:
• 1771-OW • 1771-OA
• 1771-OWN • 1771-OAD
Encoder Wiring
Encoders must be line driver type, quadrature or pulse, 5V DC or
8-15V DC output, single-ended or differential and capable of
supplying a minimum of 10mA per channel. Maximum input
frequency is 125 kHz. Encoder inputs (TB3, terminals 31-36) cannot
be used if Pulse Train inputs (TB2-7, 8) are being used.
