The MTT MS3104 is a terminal block type high-level signal conditioner (isolator) with two independent, isolated outputs. It accepts DC current (100µA to 200mA, with options such as 4~20mA, 2~10mA, 1~5mA, 0~20mA, 10~50mA) or DC voltage (200mV to 600V, with options such as 0~1V, 0~5V, 0~10V, 1~5V, ±5V, ±10V), with a maximum continuous input of 30V DC (voltage) or 40mA DC (current).
Output 1 and output 2 are independently configurable to 0~20mA current (span 4~20mA) or -10 to 10V voltage (span 10mV-20V) – useful when one signal needs to feed a PLC and a second, separate signal needs to feed a recorder or indicator at the same time. Accuracy is better than ±0.1% of span at 25°C±5°C, with temperature effect better than ±0.2% of span per 10°C change. Standard response time is 85ms max (0-90%); a /K option brings this down to 10ms for faster processes. CMRR is 100dB min (500V AC, 50/60Hz).
There is 5-way isolation between input, output 1, output 2, power, and ground, with dielectric strength of 2000V AC for 1 minute (500V AC between outputs) and insulation resistance of 100MΩ min at 500V DC.
Power supply is flexible: 100-240V AC, 24V DC (±10%), 110V DC, or 12V DC (±20%), drawing 6.5VA (AC), 1.6W (24V DC), 2.5W (110V DC), or 1.3W (12V DC). The unit mounts on DIN rail with M3.5 screw terminals, measuring W49.8 × H102.0 × D40.0mm.
