I plan to monitor

alarm contact signals (HH, H, L, LL) by just installing a pair of

One of the
AYDV's input signals is limited to 1-5Vdc. Our customer wishes to
have both inputs 4-20mA DC. Can we use the resistor module? |

We are fish
farmer. There are 2(two) illuminating lamp beside a farm pond and
these lamps are turned on all the time. For prompt system recovery
purpose, we’d like to have alarm contact signal when the lamps
could be run off or failure. Does M-System have any limit alarm
unit for this purpose? We are using 60W illuminating lamp that is
supplied 100V AC power input. |
