User programmable for... input scaling, output rate, output division, additive or subtractive totalizing, demand intervals, sliding window sub-intervals, present demand calculation period, and demands corrected to a one hour base or not.

Smart display...eight digits are provided for the total pulse count and six digits are utilized for the totalized demand readings. When the unit displays demand readings, the eighth or left most digit will display a letter code to indicate the type of demand being displayed. The model 100T will also display scaling factors for both channels, the selected output rate, the output division factor, additive/subtractive modes of operation, the total pulses on channel 1 and the total pulses on channel 2. Whenever the unit is limited by the selected output rate and is holding pulses in storage for future output, the display will flash until there are no more output pulses in storage.

Controllable display...a 3-position read switch is provided to control the display. When the switch is in the up position, the display will indicate channel 1 and then scroll to the total pulse count for the channel. In the mid-position, the display will indicate channel 2 and then scroll to the total pulse count, additive or subtractive, for the channel. In the bottom position, the display will scroll through the totalized pulse count and the three totalized demands. A three position dip switch is also provided and any one of the three demands can be eliminated from the totalized scroll routine by operating the appropriate rockers on the switch.

Debounce input circuitry...KYZ inputs drive RS flip flop latches to prevent false counts from bouncing contacts. Form A inputs are conditioned with 30 millisecond delay timing.

Bi-color LED's...monitor the state of the pulse input channel and the output relay.

High pulse acceptance rate... the Model 100T can accept input pulses as high as 720 per minute on each channel for a combined acceptance rate of 1440 pulses per minute.

High pulse storage capability...when the combined input rate exceeds the programmed output rate, the unit will store the pulses until it can output them without exceeding the selected rate. The Model 100T can store over one billion pulses for output at a later time.

Reset push button...is provided to reset the peak demands and to display the selected scaling factors, output rate, and output division factor.

Bi-color LED's...monitor the state of the pulse input channel and the output relay.

Backup memory power...the standard design uses a capacitor to provide carry-over power for greater than a four day period.

Switch selectable demand intervals ...demand intervals from one to sixty minutes are switch selectable in one minute steps.

Line frequency time base...the demand interval is derived from the power line frequency.

Diagnostics...three different test routines are provided to ensure proper operation. The unit will verify proper operation of the EPROM program, RAM, and display system.

Surge protected output contacts...RC networks are applied in parallel to output contacts to control the rate of voltage rise across the contacts during circuit opening. The standard design will provide contact protection up to 300 volts and 0 to 100 MA. Where your requirement is greater than 100 MA, please specify the expected load current and voltage and the proper contact protection will be provided at no additional charge.
