PRESET C Presets count register(s). Low level causes preset.
For single ended Preset inputs, only Preset 1C+ and/or Preset 2B+ are
used. Preset 1C- and 2C- are not connected. Differential input encoders use
both plus (+) and minus (-) inputs.
OUTPUT
RESET 0
Low level resets Outputs 1A, 1B, 2A, and 2B to OFF if latched.
For single ended Reset inputs, only Reset 10+ and/or Reset 20+ are used.
Reset 10- and 20- are not connected. Differential input encoders use both
plus (+) and minus (-) inputs.
ENABLE Low level enables counting.
For single ended Enable inputs, only Enable 1+ and/or Enable 2+ are used.
Enable 1- and 2- are not connected. Differential input encoders use both
plus (+) and minus (-) inputs.
VREF Field input device power source connection. Also, connect any unused (+)
inputs to the group VREF terminal or the one in use (30 Vdc max).
Group A = Terminal 17
Group B = Terminal 37
Group A and Group B VREF supplies can be different voltage levels.
LO FILTER
SEL
Enables the internal 200 Hz filter when connected to Return Terminal 39.
OUTPUT Internal FET switches connect the output supply wired to Terminal 40 to the
Output 1A, 1B, 2A, 2B terminals at output assert times.
POWER
SUPPLY
External 24 Vdc power supply (+) connection. Required for the module
interface and for Outputs 1A, 1B, 2A, and 2B.
RETURN External 24 Vdc power supply (-) connection. Required for the module
interface and for Outputs 1A, 1B, 2A, and 2B.
