EM-M50 can be installed to standard 96*96 millimeter slot. Each of the 8-channels can be set to activate either with opening or closing contact. Inputs can be controlled with voltage signal also. The indication output display the state of the input in realtime so the unit is s.c. transparent. Indication outputs can be inverted as well, then the output is reversed compared to input. The alarm logic operates in following manner. When the fault signal is detected, the indication light of the particular channel starts to blink and group alarm relay and alarm output gives an alarm. If the fault causing the alarm is removed the alarm stays. The alarm can be removed only with reset button. When the alarm is acknowledged the group alarm is removed, indication light stays lit until the input situation has been normalized. So new alarm blinks and old one stays lit. The alarm input can be delayed for 0.5 to 4 seconds. Alarm output can be delayd for 0 to 10 seconds. Delay is the same for all channels. Operation of the unit can be verified with test button. EM-M50 is equipped also with test and reset inputs. With these inputs several units can be connected in parallel to form groups. The group alarm relay is de-energized when alarm occurs so an operating voltage failure causes an alarm as well. Operating voltage input is protected against voltage surges and inversed voltage.
