CREMS 6 Port Monitoring Device

This is a picture of a 6 port CREMS

  • Web enabled HTTP/HTTPS
  • 6 x Digital Inputs (Modular)
  • 4 x Digital Outputs
  • 2 x Access Control Ports
  • 1 x LCD Port for viewing alarm notifications

The primary aim of the UTH-3 CREMS Devicec is to produce a cost effective monitoring and control solution across 2 server racks for power, environmental and physical access control parameters using a single IP address, to allow users to monitor and control external devices via a network attached unit.


  1. SNMP agent specifically aimed and optimised for rack management, where all I/O and control functions may be monitored and controlled through the SNMP protocol

  3. Ideal for per cabinet or per two cabinet installations

  5. Supports up to 4 intelligent PDUs (Power Distribution Units) / HE-Amp channels, 6 sensors, 2 output relays and 2 access control channels

  7. Supplied as a 1U, 19” rack mountable unit

  9. Designed to conform to the relevant CE and UL, FCC certification standards

The UTH-3 is a network attached device, which may be controlled and monitored over a TCP/ IP 10/100Mbps Ethernet network through SNMP, HTTP, HTTPS, and is capable of monitoring sensors and controlling ppower distribution units (PDUs) and output relays, allowing other network attached devices to interrogate and send commands to the UTH-3.

To achieve flexibility with a focus on security, ease of use and increased monitoring support, the UTH-3 supports a maximum of four monitor and control power strips, supporting both RS232 and RS485 serial port communication protocols, which will monitor volts, amps, kVA, kWHr, power factor and frequency from the power strip.

Further to this, the UTH-3 also supports two serial keypads, or smart card readers, to control access to the cabinets via solenoid or motorised activated door locks, one external LCD display unit and six sensor inputs, which may be any combination of temperature, humidity, voltage free contact sensor and 0-10VDC analogue input voltage.

The UTH-3 also supports an intuitive web based graphical user interface, eliminating the need for complex serial setup processes. The web server within the unit supports HTTP/HTTPS network protocols, allowing the user to securely configure,
monitor and control the UTH-3 via a username and password access control system.
