can be selected. Scaling
can be as follows:
0...10 V corresponding to a temperature range selected within
the working temperature range (e.g. 50...80°C)
minimum load 4 kOhm
or
0...6 V = -200...400°C = 10 mV/K
0°C = 2 V
or
0...10 V = -100...400°C
or
0...10 V = 0...100°C
Pin 2: voltage output temperature signal channel 1, other data as pin 1
Pin 3: ground for all signals
Pin 4: setpoint voltage input; scaling can be selected as pin 1. R
i
=
12 kOhm approx.
(+ pin 4; - pin 3)
Pin 5: current output temperature signal channel 1; signal selection as
pin 1. Can be configured for 0...20 mA or 4...20 mA. Scaling can
be:
0...20/4...20 mA = -100...400°C
or
0...20/4...20 mA = 0...100°C
or
0...20/4...20 mA = a temperature range
selected within the
working temperature
range
(e.g. 50...80°C)
maximum burden 330 Ohm
Connect only either pin 2 or pin 5!
Pin 6: setpoint current input; configuration and scaling as pin 5.
Burden 320 Ohm approx. Maximum voltage 15 V!
Connector plug, 6-pin Cat. No. EQS 057
Use shielded connecting cables. Connect the shielding to the plug case. The mass for
all signals (pin 3) must not be connected with ground! If a connection to the ground
cannot be avoided use a potential-free signal bridge in between.
Cover the unused connectors with protective caps!
