Series 684 indicator alarm module

Available in various sizes and with up to eight channels in a single NEMA 4X enclosure, the Series 684 indicator alarm module is an economical solution to the issue of machine shutdown protection, as increased vibration levels portend potential failure. Directly interfacing with ICP piezoelectric or 4–20-mA sensors, the system is universally-powered and provides appropriate excitation voltages. Each indicator channel contains upwards of four form C relays for alarm and shutdown control. In addition to time delay options, the system features push-button programmable settings that ease set-up and prevent false alarms. The front of each unit has indicator lights that display relay status. The meters integrate acceleration signals, and display the units in acceleration, velocity or displacement. Positioned on the front of each module, BNC connections access raw vibration signals for easy interface with data collection equipment. The system can retransmit a signal for straightforward interface with existing PLC, DCS and SCADA systems.
