Analog Output Unit
The Analog Output Unit of V-RTU2000 Series is designed with one
card which is AO Card (Analog Output), in which each PC board
provides 4 Differential Channels (CH1+/CH1- ~ CH4+/CH4-) and 2
Shielding Points (S1, S2). The card type provided by V-RTU2000
Series are as listed below:
AO Card (+/-1mA): Analog Output Card, 4 Differential Channels /
Card, Output Range +/-1mA.
AO Card (4~20mA): Analog Output Card, 4 Differential Channels/
Card, Output Range 4~20mA.
For application, AO Card is normally used to execute the Analog
Raise/Lower
AGC
raise/lowering setting of the generator set.
Analog Output Card is an intelligent IO Card, which is used to
execute the Analog Raise/Lower Output control. It contains CPU
comply with its Firmware, it also provides interface and converting
circuit for analog output conversion. It connects with CPU Card
through LIOC RS-485 communication interface, the DATA & /DATA
Communication Signal is linked by the backplane without additional
wirings. The external connection contains 4 Differential Input
Channels (Ch1+/CH1- ~ CH4+/CH4-) and 2 Shielding (S1, S2),
which are transmitted through 96-Pin DIN Connector to 10-Pin
terminal on the backplane for actual application. In principle design,
the analog and digital circuits are isolated.
