USB-keskitin EXSYS EX-1194HMS

The EXSYS EX-1194HMS is a compact USB 3.2 Gen 1 (USB 3.1 Gen 1) metal hub designed to expand one USB-B host port into four downstream ports: one full-featured USB-C and three USB-A connectors. It supports data transfer rates up to 5 Gbps, provides ESD surge protection for all ports, and is built to meet requirements of automation, office and industrial applications. The hub accepts a wide input voltage range and can be mounted in a 19-inch rack or on DIN-rail for flexible installation.

Advantages

The EX-1194HMS offers a mix of USB-A and reversible USB-C ports for broad device compatibility and easy cable connection. All ports include 15 kV ESD surge protection and support protection against voltage fluctuations. The hub supports up to 900 mA USB bus power per port, fast USB charging modes (CDP and DCP), and optional +5 V bus power. Compact metal housing and included DIN-rail kit simplify installation in industrial and rack environments.

Suitable for

• Connecting multiple USB 3.0/3.1 peripherals to a single host port
• Industrial control and automation systems requiring rugged, surge-protected USB expansion
• Office workstations and 19-inch rack installations
• Charging and data transfer for USB-C and USB-A devices

How to use

Mount the hub using the included DIN-rail kit or install it in a 19-inch rack as required. Connect the hub's USB-B upstream port to the host computer using the supplied USB cable. Attach downstream devices to the USB-C or USB-A ports. Supply DC power within the specified +7 to +48 V range via the terminal block to enable higher bus power and charging features when needed. Observe correct cable orientation for non-reversible connectors; the USB-C port supports reversible plug orientation.

Recommendations

Use shielded USB cables and a stable DC power source within the specified voltage range to ensure reliable data transfer and to protect connected devices. For industrial installations, secure the hub to the DIN-rail and verify grounding to maximize ESD protection.
