Option
G04
(peripheral board 3) provides in addition to standard
converter terminals:
•
2 analog outputs (AO) 4 to 20 mA/0 to 10 V
•
One digital input "Safe Torque Off" (STO, single-channel or
two-channel) acc. to EN ISO 13849-1, Cat. 3 or SIL 2
acc. to EN 61508
9 digital inputs (DI)
•
3 relay outputs (DO)
In addition, the relay outputs here are not only isolated from
the converter electronics but also from each other.
•
24 V / 300 mA power supply unit
SIL 2 (acc. to EN 61508) – STO (Safe Torque Off).
安全的转矩(国标)函数tion implemented according to
SIL 2 to EN 61508.
The "Safe Torque Off" (STO) function has a redundant switch-off
path in the converter. The implementation is performed using
hardware. A relay in the power unit of the converter disconnects
the power supply of the IGBT driver. A second circuit, also via
hardware, produces a controller disable.
The "Safe Torque Off" input can be implemented with either one
or two channels. The board is coded for single-channel activa-
tion at the factory. If two-channel activation is required, please
specify this in the order. Digital input X2:24 is reserved for the
two-channel version.
Standard assignment of inputs/outputs

function of interfaces in the pin assignments for the "Standard"
application.
NAMUR-compliant assignment of inputs/outputs
The table below provides an overview of the pre-assignment
function of interfaces in the pin assignments for the "NAMUR"
application.
