B&C Electronics pH 7687

Range
0.00 ÷ 14.00 pH
-2000 ÷ 2000 mV
-10.0 ÷ 110.0 °C, 14.0 ÷ 230.0 °F

Display
The multi-line graphic display shows the values of the
measures and the messages which guide the user through
set-up, configuration and during normal operation.

Keyboard
There are dedicated keys to directly access zero and
sensitivity calibration as well as set point configuration.

Operating mode
The meters can operate in automatic, measure or simulated
mode so to facilitate start-up or maintenance.

Two filters software
The user can set two filters in order to obtain a stable reading
and a faster response to the variations of the measurement in
the process.

Two analog outputs
Can be addressed to any input and programmable 0/4 – 20
mA on two points of the scale. They allow PID control or
transmission of the measured values.

Two On/Off regulators
Independent and addressable to any input with
programmable set point on the scale.

PID output
During PID control through the analog output, the level of the
actuation is displayed.
The user can select an FM regulation (pulse frequency) or WM
(pulse width) addressed to the assigned relay.

Alarm
The relay is dedicated to min/max values of the measures,
the excessive activation of relays and the presence of the
logic inputs.

Logic inputs
Two free voltage contacts can generate a hold or alarm
condition.

Autocleaning
A relay is dedicated to an external device for the sensor selfcleaning.
This function is fully programmable through the
controllers’ software.

Universal power supply
From 85 to 264 Vac, 50/60 Hz.
The low voltage option allows to power the unit from 9 to
36 Vdc or from 12 to 24 Vac, 50/60 Hz.

Easy installation
All 6587 series of controllers have IP65 protection rating.
They are suitable for wall mounting, or for DIN rail and
handrail by means of optional accessories.
Series 7687 has an IP65 front panel and it is designed for
customers who prefer panel mounting.

Compatible and versatile
The analyzers are compatible with all B&C Electronics’ pH
(glass or antimony) and ORP sensors.The temperature measuring and compensation is done with
Pt100 or Pt1000 two or three wires probes.
