About the 3020-IOM-4411-20
PowerLogic 3020-IOM-4411-20 is an I/O (Input/Output) module that can store minimum and maximum values for real-time readings. These readings are stored in nonvolatile memory at regular intervals. The user can configure up to 14 data log files. The 3020-IOM-4411-20 can provide a variety of demand readings, including predicted demands and coincident readings.
The 3020-IOM-4411-20 has 4 status IN, 1 KYZ pulse OUT, 3 Form-C relay OUT, 1 Analog IN, and 1 Analog OUT (0-1 mA.) Analog inputs are 0-5Vdc, but it is possible to configure each analog input to accept a 4-20 mA input by connecting an external jumper wire.
All status input transition events on the 3020-IOM-4411-20 are time stamped with resolution to the millisecond, for sequence of event recording.
It is also worth noting the KYZ output is a solid-state relay Form-C contact designed for long life. Pulse initiator applications require this kind of relay.
The 3020-IOM-4411-20 can be used as part of a 2-wire or a 3-wire pulse initiator application. In most two-wire KYZ pulse applications, only one side of the Form-C contact is used. In a two-wire application, the circuit monitor can deliver up to 5 pulses per second. Three-wire KYZ pulses are transitions between KY and KZ; these transitions alternate contact closures on a Form-C contact. In a three-wire application, the circuit monitor delivers up to 10 pulses per second.
The PowerLogic 3020-IOM-4411-20 is able to detect over 100 alarm conditions. It is worth noting, however, that many of these alarm conditions (including all under, over, and phase unbalance alarm conditions) require defined setpoints with a pickup setpoint, a pickup delay (in seconds,) a dropout setpoint and a dropout delay (in seconds.)
The 3020-IOM-4411-20 mounts with seven screws. Type 1 enclosure. Indoor use only. There is a relay diagram on the back of the unit.
