Performance and Signal Handling

• The module supports symmetrical incremental encoders with two pulse trains offset by 90 degrees.
• It also accepts asymmetrical incremental encoders, 24 V initiators, and 24 V directional elements.
• Input delay for standard inputs is parameterizable, with a maximum frequency of 200 kHz.
• Digital inputs respond to signal "0" from -28.8 V to +5 V and signal "1" from +11 V to +28.8 V.
• Digital outputs provide signal "1" at minimum 2L+ (-1.5 V) and signal "0" at maximum 3 V.
• Short-circuit protection exists on both encoder supplies and digital outputs.
• The counter input 5 V uses RS 422 with a 220 Ω terminating resistor and 0.5 V minimum differential input.

Environmental and Installation Notes

• The module operates with a permissible potential difference of 75 V DC or 60 V AC between circuits.
• Potential separation between channels and backplane bus uses optocouplers for inputs, outputs, and counters.
• You need one 48-pin front connector for proper wiring and connection.
• Status indicators include 14 green LEDs for CR, DIR, inputs, and outputs.
• Two red LEDs show internal and external errors for fast diagnostics.
• Diagnostic alarms and hardware interrupts are parameterizable for flexible system integration.
• The load voltage inputs 1L+ and 2L+ both offer reverse polarity protection.
