All 22 inputs can be configured to measure 0-25mA, 0-10V, or Thermistor Analogue input circuits, or can measure volt free digital inputs. Configuration is via a small jumper

4 field effect transistor (FET) digital outputs with built in short circuit, overload, and over temperature protection. These outputs are capable of driving lamps, bulbs, or external relays up to a current of 1.5A

4 field effect transistor (FET), pulse width modulation outputs with built in short circuit, overload, and over temperature protection

4 0-10V analogue outputs. These outputs are capable of controlling dampers in ventilation systems, valves on boilers or radiators, fan speed controllers and indicator lamps

4 Mains rated relay outputs. These outputs are capable of driving external systems, such as boilers, solenoid valves and pumps that operate on up to 240VAC. They also offer a solution for isolated switching for any type of switching, eg lighting control and alarm systems

4 digital frequency inputs with counters for measuring and counting pulse inputs up to 2KHz. These inputs are capable of measuring signals from devices that give a pulse output, eg flow meters, gas, water and electricity meters and engine speed transducers

Optional GSM/GPRS modem provides a wireless connection to the Internet

Optional V22 modem allows connection to the Internet via a standard phone line (Please note a dial up ISP connection must be provided)

10 Base-T Ethernet controller for connecting to the Internet via a corporate LAN or via your home broadband connection

RS485 serial port for attaching external IO modules

2 RS232 serial ports for attaching to third party devices, eg GPS receivers, external displays, BMSs, and other monitoring equipment

USB diagnostics port to alter settings and provide IO diagnostics to ease installation and to aid with local fault-finding

8 LED status indicators provide local diagnostics information

Audible sounder, which can be activated in response to any sensory input
