In addition to the sensor, ETSD1 contains a microcontroller circuit which calculates the difference between thetwo temperatures (T1-T2), and outputs it via an amplifier as a 4..20 mA signal. Two outputs with different characteristic curves areavailable as standard.Altogether the circuit requires < 4 mA, and so it was possible to implement a 2-wire system (including wire break recognition).pi-ho-te-etsd_e V1.02-01Supply voltage Materials medium-contact Materials, nonmedium-contact Analog outputReversal polarity protected Electrical connection Ingress protection WeightConformity15..30 V DC 1.4571 CW614N plated, PP 4..20 mA (two-wire) yes plug DIN 43650-A / ISO 4400IP 65 0.45 kg CE1
