DIEL MT 200 E Manual De Instalacion Y Uso página 19

Inputs
• Four analogue inputs, temperature detection and control with three-wire
PT100 probes in the range from -10 to +200°C.
Outputs
• Four 250 VAC 10 A maximum (resistive load) relays, 1 clean changeover
contact.
• ETHERNET communication port, MODBUS-TCP protocol (MT 200 E)
Characteristics
• Self-extinguishing NORYL container.
• Front panel protection grade in polycarbonate: IP65 (IP66 on request)
• Protection level of rear panel on terminal block side: IP20
• Display with light segments
• Automatic display of the value and number of the probe relative to the
warmest channel.
• Pre-alarm, alarm, probe failure, ventilation, manual operation and historical
maximums signals.
• Access to the control unit programming directly from the front panel.
• Possibility of independently selecting each individual channel.
• Alarm and pre-alarm threshold settable in the range (-9°C÷199°C).
• Accuracy ± 1% on full scale value ± 1 digit.
• Management of the cooling fan on all channels.
• Fan control by hysteresis with two temperature values (H and L).
• Five selectable operating modes.
• Faulty probes recognition, maximum management flexibility and simplicity of
programming, checking the validity of the data introduced during the
programming phase.
• Permanent storage of the programmed values and the data reached by each
channel (historical thresholds and maximums).
• Dielectric strength between the relay contacts and 2.5 KVAC power line for
60".
• Possibility to use the probes to thermostat the environment.
• Resolution 1°C
• Control unit working temperature from -40°C to +60°C.
