Input/Output Module Connectors
Users can choose different types of analog and digital input/output modules that can be
Input/Output
module types
installed on the rear panel of 61000. The modules must be selected at time of order. In case
users want additional modules installed, the unit must be returned to the factory. The input/
output modules allow a variety of voltage and current measurement cables, probe types, or
pods to connect to the instrument for voltage, current, and/or digital signal monitoring.
The voltage and current connectors are designed in modular configuration, with the
following analog input module measurement point interface:
• AC/DC Voltage Module with safety connectors (Model 61MVB)
• AC/DC Voltage Module with terminal block connectors (Model 61MVS)
• AC/DC Current Module with connectors for external CTs (Model 61MAC)
• AC/DC Module for Voltage or Current Pod (Model 61MZP)
The eight-channel digital input module Model 61MDIN allows users to monitor on/off type
digital signals, such as breaker or switch signal positions. Digital inputs can be configured
to provide demand interval synchronization, pulse counting, KYZ metering, or to provide
start/stop monitoring control.
Digital output module allows certain events to result in change of state of a relay contact.
See Appendix A for specifications of Dranetz-BMI digital output module Models
61MDOH and 61MDOL.
Transducer input module Models 61MXVS and 61MXAS can record and trigger on
analog signal levels in either the 0-24V and 4-20mA range respectively.
Input channels for the modules installed on the rear connector panel are labelled ±A, ±B,
Input channels
±C, and ±D. You must turn on any input channel to be used for monitoring. If a channel is
not turned on, no data will be collected for it.
