Schneider 140EHC20200 | High-Speed Counter Module

The Schneider 140EHC20200 provides precise high-speed counting for the Modicon Quantum platform. This module features two independent counter channels for versatile applications. It accepts input frequencies up to 500 kHz per channel for accurate position tracking. Weighing only 0.45 kg, the Schneider 140EHC20200 fits into any standard Quantum rack slot. Its dimensions measure 150 mm x 100 mm x 55 mm.

Input Interfaces and Signal Types

The Schneider 140EHC20200 accepts five different input signal types for maximum flexibility. This module handles RS422 differential signals, 5 V DC, and 24 V DC inputs. It also supports 24 V DC directional signals and 5 V DC encoder interfaces. Moreover, each channel includes dedicated digital inputs for counting enable and preset functions. Therefore, you can configure this counter for nearly any industrial sensor or encoder.

Energy Storage and Internal Components

The Schneider 140EHC20200 contains no internal battery for maintenance-free operation. It stores configuration data in non-volatile flash memory instead. This module includes four optocouplers for input isolation and noise rejection. The unit draws 350 mA from the 5 V DC rack power supply. Consequently, it adds minimal load to your existing Quantum system. The Schneider 140EHC20200 also features four discrete outputs for setpoint control.
