ACT20M-AI-AO-E-S Details

Configurable ACT20M AI-AO U/I DC converter/supply isolator and ACT20M-AI-2AO signal multiplier: with 6.1 mm width and external power supply for transmitting and isolating analogue DC current and voltage signals. The universal input and output parameters can be configured as required using the DIP switches. The input/ output channel(s) and power supply have 2.5 kV of electrical isolation.

The universal ACT20M-AI-AO-S supply isolator can feed power directly from the input loop signal to passive sensors. ACT20M-AI-2AO-S with 4-way isolation is designed as a signal splitter. The input signal is doubled on the output side. It can be transmitted simultaneously to a controller and an external display.

High precision of < 0.05% of measurement range, wide temperature range of -25°C (0°C)...+70°C and international approvals (cULus, ATEX Zone2, FM Div2, GL, DNV) mean the device can be used in many applications around the world.

The power supply can be easily and quickly installed using the CH20M DIN rail bus. The power can be supplied using any ACT20M module (up to 20 devices) or a separate ACT20 supply module (up to 200 devices).
