Works With Virtually Any Flow Meter -
The standard ﬂow input of the D-100 accepts active or passive 4 – 20 mA, active or passive pulse and contact closure ﬂow signals.
Serial Communications -
Optional communications card provides all rate and total data to the control system through a single network connection, reducing installation costs.
Supports a Wide Variety of Communications Protocols -
The D-100 can be provided with any of the following network interface options:
• BACnet MS/TP
• LONWORKS FTT10
• MODBUS RTU-RS485
• MODBUS RTU-TCP/IP
• Johnson Controls Metasys N2
• Siemens Apogee P1
Suitable for Bi-directional Applications -
The D-100 accumulates separate totals for ﬂow in each direction. The totals may be read locally on the display or remotely via an optional network interface.
Simple Installation and Commissioning -
The D-100 is factory programmed and ready for use upon delivery. All programming functions are accessible via front panel display and keypad.
The D-100 is a totalizing display module that provides a local indication of liquid or steam ﬂow rate and total data. The ﬂexible design can also be conﬁgured with an optional network interface to communicate ﬂow data to the building control network. It is housed in a steel wall mounted enclosure with a built-in user interface/display. The standard ﬂow input accepts 4-20 mA, pulse or contact closure ﬂow signals. The versatile D-100 can also function as a network interface for 2 additional analog rate inputs and one additional totalizing pulse input. It can also be conﬁgured with up to 4 optional analog outputs.
