Digital units are equipped with a 15 pin D-subminiature female receptacle on

the right side of the power box. An ENABLE/DISABLE switch is located just

below the receptacle. Place the switch to the ENABLE position to control the

bath via the receptacle connection. (The sensor temperature and setpoint, pin

7 and 8, can be read with the switch in either position.) The pin-out information

is listed below.

1

Chassis ground.

2

No connection.

3

Span +. Indicates the maximum setpoint value the unit can be set
to operate. The temperature scale is 10mV/°C, referenced to
analog ground, pin 6 (example: +350mV = +35.0°C).

4

Span -. Indicates the minimum setpoint value the unit can be set
to operate. The temperature scale is 10mV/°C, referenced to
analog ground, pin 6 (example: +50mV = +5.0°C).

5

No connection.

6

Analog ground. The analog ground is physically separated from
the power ground throughout the unit. To prevent offsets that
result from ground currents, the analog and power grounds are
only connected at the unit's power supply. Analog ground should
only be used as a reference pin.

7

Sensor temperature (current limited through 2.7K OHM resistor).
The fluid temperature, as measured by the controller’s sensor
located in the reservoir, can be read at this pin. The temperature
scale is 10mV/°C, referenced to analog ground, pin 6 (example:
+150mV = +15.0°C).

8

Setpoint out. The present temperature setpoint can be read at
this pin. The temperature scale is 10mV/°C, referenced to analog
ground, pin 6 (example: +150mV =  +15.0°C).

9

Power Ground.

10

No connection.

11

No connection.

12

Digital display (input only). An external voltage can be displayed
on the operator panel digital display by applying the voltage to this
pin. The display has a low input resistance and a full scale rating
of ±1.99VDC. Input is referenced to analog ground, pin 6. The
maximum voltage applied to the display should be limited to
±2VDC.

13

- 5V. Power supply of -5VDC (15mA maximum).

14

+5V. Power supply of +5VDC (50mA maximum).

15

Setpoint in. The temperature setpoint can be controlled by
applying a known voltage to this pin. The temperature scale is
10mV/°C, referenced to analog ground, pin 6
(example: +230mV = +23.0°C).

NOTE: With the switch in the ENABLE position and no input to pin 15, the bath will slowly go to
the setpoint value set on the digital controller.
