HT MC2 - Microprocessor Regulator for 2 Control Circuits
This compact regulator for the mounting on a DIN rail has a couple of special features:
• very compact dimensions: 110 x 70 x 72 mm (L x W x H)
• easy to install due to the connection with detachable contact strips
• at 230 V~, heater powers of 2 x 600 W (triacs) or 2 x 1500 W (mechanical relays) are switched internally, without additional circuit amplifiers
• external set-point setting via 4 - 20 mA current signals
Further features are possible: different temperature sensors, self-optimizing regulation parameters, potential-free signal contact adjustable for each channel, digital display for nominal value / actual value as well as nominal value limitation between 0 and 250 °C.
The following operation modes are possible:
• Mode 1: Regulation of two heating circuits
For switching the load, two electrical triacs and two mechanical relays are integrated. When the internal triacs are used, the heating current is additionally passed through the mechanical relay. In case of an error (sensor break, excess temperature), the heatings are mechanically cut off from the mains..
• Mode 2: Regulation and supervision of one heating circuit
One heating circuit operates with two temperature sensors: sensor 1 measures the regulation temperature, sensor 2 monitors the limiting temperature. This mode is especially suitable if the section to be regulated reacts very slowly and controlling the maximum temperature of the heating element is particularly important during the heating-up period.
• Mode 3: Regulation and limitation of one heating circuit
One heating circuit operates with two temperature sensors: sensor 1 measures the regulation temperature, sensor 2 a limiting temperature (can be adjusted to a value which is 1 to 20 K higher than the nominal temperature at sensor 1). When the limiting temperature is reached, a mechanical relay cuts the heating permanently from the mains. A restart is possible by a reset. Please note: due to the fact that the sensor signals are handled in one single processor, the device must not be used as a (safety) temperature limiter.
