PLCs, Power Supplies & Others

This Modicon counter module captures high-speed pulse signals for Schneider PLC systems. It counts incremental encoder signals or digital pulse trains accurately. Therefore, this component suits positioning, flow measurement, and length counting applications.

Physical Dimensions and Weight Specifications

The Schneider ZAE 201 occupies one standard slot in the Modicon rack. Its housing measures 220 mm in depth for backplane connectivity. The module weighs approximately 0.42 kg for straightforward handling. Consequently, technicians can install this unit without additional rack reinforcement.

Interface Types and Connection Layout

The Schneider ZAE 201 provides a 48-pin front connector for sensor wiring. A 20-pin backplane connector supplies power and data from the CPU. The front panel carries LED indicators for each counter channel status. Hence, operators can verify counting activity at a quick glance.

Component Count and Channel Configuration

This counter module contains one main board with two independent counter channels. Each channel includes a 24-bit counter register for high-range values. You will also find four digital inputs for gate and reset functions. An onboard comparator triggers outputs at preset count values.

Energy Storage and Power Consumption

The Schneider ZAE 201 draws 110 mA from the 5V backplane supply. A small supercapacitor retains current counter values for 24 hours. This energy storage protects position data during unexpected power cycles. Therefore, the module resumes counting without re-homing after restarts.

Counting Modes and Operational Flexibility

Users can configure each channel for up/down or directional counting. The module also supports one-shot and periodic pulse generation. A programmable digital filter rejects noise pulses below 50 microseconds. This feature ensures accurate counts in electrically noisy factory environments.
