Plug-In Digital Alarm Setter

Model: MS5505DMS5500

DESCRIPTION

51The MS5505D is a plug-in digital alarm setter that compares
the levels of DC current or voltage signals with twoset-points (upper and lower limits) and outputs two
independent isolated relay contact closure signals.

Output SignalORDERING INFORMATION
To place an order, please use the ordering code format
as shown above.
(e.g.) MS5505D-A-6OHOL* The factory default trip point for both channels is 50% or
equivalent of input span.
Other Ordering Examples:
For an option code of “X”: MS5505D-A-6OHOL/X(Response time constant: T = 50ms with 90% setting)
For specific trip points*: MS5505D-A-6OHOL
Trip point for Output 1: 40%
Trip point for Output 2: 70%* Specify values in % within the range of 0 to 99% of input
span.
Note: If you wish to include multiple options in your order,
specify the option codes in series (e.g. /KX).
