5.4
Outputs
Two output signals are available which may be configured for ON/OFF or PWM outputs through the Output Configuration
registers 0x0124 and 0x0126 (Modbus 0xf092 and 0xf093).
Note:
The Output Drive Type (Open Drain, inverting driver) is fixed.

5.4.1
PWM Rate
The SP-005 probe outputs support the following PWM frequencies:
5.4.2
Active State
The SP-005 probe outputs may be configured as Active HIGH or Active LOW. When set to 1 (Active HIGH), the output
will be high impedance when active. When set to 0 (Active LOW), the output will be low impedance when active. The
5.4.3
Factory reset value is 0.
Output Drive
The Output Drive is permanently set to 3, indicating that the output is configured as an Open Drain driver, allowing
5.4.4
the DIN signal to override and read back the state of the output signal.
Output Type
The SP-005 probe supports NULL (0), ON/OFF (1) or PWM (2) outputs. When set to NULL the output signal will be left
in a high impedance state. When set to ON/OFF the Rate information has no affect.
