The following table describes the functions and characteristics of the pump switching option card control terminals.

Function	Characteristics
Available DC Power Supplies	Protected against short circuits and overloads
	2 outputs, +10 Vdc and -10 Vdc
+10 and -10
	Maximum current = 10 mA each
	3 reassignable logic inputs. Impedance = 3.5 kΩ . Compatible with
	Level 1 PLCs according to IEC 60065A-68. Maximum shielded
Digital Logic Inputs	cable length: 330 ft (100 m).
DI5, DI6, DI7	Supply: +24 V (11 V min., 30 V max.)
	State 0 if < 5 V, state 1 if > 11 V.
	The logic inputs are sampled every 2 ms, maximum.
	4 reassignable open collector logic output, compatible with Level 1
Logic Outputs	PLCs according to IEC 60065A-68.
	Supply: +24 V (12 V min., 30 V max.),
DO1, DO2, DO3, DO4
	maximum current = 200 mA each with external source.
	The logic output is updated every 2 ms, maximum.
	1 reassignable 0–20 mA analog output
	Maximum load impedance = 500 Ω .
Analog Output	Resolution: 0.04 mA (9 bits)
AO	Linearity: ± 0.1 mA
	Accuracy: ± 0.2 mA
	The analog output is updated every 2 ms, maximum.
	1 reassignable, ±10 V bipolar differential input.
	Input Impedance: AI3A to AI3B > 300 kΩ .
	AI3A to COM ≅ 30 kΩ
	AI3B to COM > 600 kΩ
Analog Input	Maximum allowable voltage: ± 30 V.
	Frequency reference resolution: 0.1 Hz for 100 Hz (0.1% of
AI3A, AI3B
	maximum frequency), 10 bits plus sign.
	Accuracy: ± 0.5%.
	Linearity: ± 0.2% of the maximum output frequency.
	The analog input is sampled every 2 ms, maximum.
	Maximum length of shielded cable: 66 ft (20 m).
COM	0 Vdc
	Common for analog input signal
COM DI	0 Vdc
	Common for logic inputs, logic outputs, and analog output
External Logic Output Power	Input: +24 Vdc nominal (12 Vdc min., 30 Vdc max.)
DO+	Maximum current = 200 mA per logic output.

[1]Maximum wire size capacity 1.5 mm2 (AWG 14). Recommended tightening torque is 3.54 lb-in (0.4 N•m).

NOTE: There is no +24 Vdc power supply output on this option card; therefore, it is necessary to connect an external +24 Vdc power source between terminals DO+ (+) and COMDI (-).
