1781 AC output

WRC4 AC output

General specifications Operating temperature range –30 to +80°C Storage temperature range –40 to +100°C Isolation 4,000 V rms Capacitance input to output 8 pF Line frequency range 47 to 63 Hz Application notes Do not install or remove modules in live (electrically hot) circuits. High voltage may be present. Output connections are non-polarized. All units, except OM_ _R, and OAC--A11 are zero-cross outputs. These modules turn on irrespective of zero crossing. All units, except OM_ _C and OAC__A5 are normally open. These modules are normally closed. The OM5MS covers the 5V, 15V and 24V logic levels.
