Schneider Electric ABE7H16R21 Passive Connection Sub-Base
Product Introduction
The Schneider Electric ABE7H16R21 belongs to the Modicon ABE7 range, a trusted family of connection sub-bases for Telefast pre-wired systems. This passive sub-base simplifies the wiring of discrete input and output signals in automation cabinets. Specifically, it connects field devices to PLC cards equipped with HE-10 connectors. The unit provides 16 channels with two terminals per channel. Furthermore, it distributes 0V or 24V polarity for flexible input or output configuration.
Technical Specifications
The ABE7H16R21 operates on a rated supply voltage of 19 to 30V DC, compliant with IEC 61131-2. It supports a maximum supply current of 1.8A. Meanwhile, the current per channel reaches up to 0.5A. For protection, a 2A internal fuse guards the PLC end. Additionally, the unit includes an LED per channel for simple status diagnostics. The HE-10 20-pin connector ensures a secure and standardized link to the PLC interface.
Mechanical and Environmental Parameters
This sub-base measures 77 mm in height and 206 mm in width. The product weight is 0.64 kg. It accepts wire cross-sections from 0.14 to 2.5 mm² for solid conductors. Moreover, the screw terminals accommodate flexible wires from 0.09 to 1.5 mm². The operating temperature range spans from -5 to 60 °C. Its IP2X protection rating conforms to IEC 60529, ensuring finger-safe operation.
Installation Guide
Installation is straightforward. First, mount the ABE7H16R21 onto a 35 mm symmetrical DIN rail using the built-in clips. Alternatively, screw mounting is possible on a solid plate with a fixing kit. Next, connect the HE-10 20-pin connector to the corresponding PLC channel. After that, wire the field signals to the screw terminals. Finally, verify the channel LEDs for status indication.
