The externally supplied ACT20M…, ACT20P… , MAS RPS/RPSH and WAS/WAZ 4/5 signal converters/supply isolators for transmitting, isolating and converting standardised DC current signals are optionally available in widths of 6 mm (ACT20M…), 12.5 mm (WAS/WAZ4, ACT20P…) or 17.5 mm (WAS/WAZ5…).
The input and output circuits and the voltage supply are completely electrically isolated.
The input signal is converted into a DC current or voltage value.
WAVESERIES signal converters are optionally available with a limiting frequency of 10 Hz (WAS/ WAZ4) or 20 kHz (WAS/WAZ5) for fast signal processing.
The MAS/RPS/RPSH supply isolators can supply external 2-wire sensors (ACT20P 2-/3-wire sensors) and are optionally suitable for transmitting HART protocols (MAS RPSH, ACT20P).
The 24 VDC supply voltage can be cross-connected on the module side via the CH20M BUS PROFILE (ACT20M series) or using the ZQV4N (MAS) or ZQV 2.5N (WAS/WAZ) pluggable jumpers. International approvals such as ATEX zone 2, UL C1D2 and FM Div2 also enable use in explosive risk zones.
