TURCK - Multi-Safe Rotational Speed Monitor Single-Channel, Intrinsically Safe Input Circuit, UnderSpeed / OverSpeed Monitor For Use in Hazardous Locations - Detailed Information Below TURCK - Multi-Safe Rotational Speed Monitor Single-Channel, Intrinsically Safe Input Circuit, UnderSpeed / OverSpeed Monitor For Use in Hazardous Locations - Detailed Information Below The MS21-12Ex0-R is a single-channel rotational speed monitor with an intrinsically safe input circuit. It is designed to monitor pulse sequences from NAMUR sensors in hazardous locations. One DPDT setpoint relay output indicates overspeed or underspeed conditions to control equipment in non-hazardous locations. The device monitors for overspeed when terminals 11 and 12 are jumpered; it monitors for underspeed when terminals 11 and 12 are open. The device has six overlapping preset ranges. The speed preset is the product of the front panel switch and potentiometer settings. The unit operates on the digital pulse principle, which provides relatively short detection times in applications where input pulses occur infrequently. A yellow LED indicates the function of the output relay. A start-up time delay (AU) is available for underspeed applications. The time delay inhibits speed monitoring and alarm indications during system start-up. The start-up time delay is adjustable from 0-60 seconds. It is enabled under two conditions: - if terminals 15 and 16 are open when power is applied to terminals 1 and 2. - upon opening of a momentary contact between terminals 15 and 16. During the start-up time delay, the output relays will be energized if terminals 13 and 14 are open and de-energized if they are linked. The switching hysteresis and start-up time delay are adjusted by means of potentiometers inside the device that are accessed by removal of the front cover.
