The EV6421M supplied by Aptifirst Ltd is a versatile and cost-effective on/off temperature controller that is designed for DIN Rail mounting, and so is very useful for use in electrical control cabinets. Programmable from the front keys, the EV6421M accepts “universal” inputs, in that it can be adjusted for inputs from NTC or PTC thermistors, Type J or Type K thermocouples, 2 or 3 wire PT100, PT1000 or Ni120 sensors, or 0-20mA or 4-20mA current loops, or 0-10V or 2-10V voltage signals. The EV6421M is available with three power supply options: 115V AC, 230V AC, and 12 – 24V DC. The large LED display may be programmed to show temperatures in degrees Celsius or Fahrenheit, and to a resolution of 0.1°C, 1°C or 1°F. The EV6421M has a relay output rated at 230V 10A resistive load, which may be wired either Normally Open (NO) or Normally Closed (NC). Additionally, it has two programmable alarms which may be set as High or Low, and as Absolute or Relative. The unit also has a user-programmable Alarm Buzzer, which is useful for signalling an alarm condition when, for example, the instrument is inside a control panel. Said Roy Carter, Aptifirst’s Managing Director, “The EV6421M is a very useful controller, and we are very pleased to offer it in our range. As well as its versatility in terms of choice of input and power supply, it is useful for notifying under- or over-temperature alarms. And it’s not just temperatures that it can control and monitor; we have used these as over-pressure and over-load alarms in some of our laboratory instruments, monitoring a 0-10V output signal. The EV6421M has a very wide range of application. It may be used for regular temperature control in production and manufacturing, for controlling test chambers and freezer cabinets, for defrost management, as a secondary temperature monitoring system with alarm monitors, process monitoring, and so on. It has uses in industries including foods, plastics, rubbers, pharmaceuticals, asphalt, defence, aerospace, defence, catering, environmental monitoring, and many, many more.”
