PPC-2030 Encoder In Analog Out Module
The PPC-2030 is used in applications including monitoring and
controlling belt speeds, motor speeds, positioning, etc.
Four isolated analog outputs are jumper configurable for
current or voltage. These outputs may be used to provide
software selectable analog output signals to field devices.
Four counter inputs are used for interfacing to motor encoder
signals. The counters interface to both single-ended and
differential styles of encoder signals and count quadrature
signals for increased resolution, accuracy and direction.
PPC-2040 Digital I/O Module
Up to four PPC-2040 modules may be added to a PPC system.
Each module includes 32 digital I/O points which are
individually configurable as inputs or outputs and two counter
and frequency inputs.
PPC-2050 - 2051 Analog Out Modules
Up to four PPC-2050 and PPC-2051 modules may be added to
a PPC system. Modules include four or eight analog outputs.
PPC-2061 - 2062 Digital Out Relays Module
Up to six PPC-2060, PPC-2061, and PPC-2062 modules may be
added to a PPC system. The PPC-2061 features 16
electromechanical relays. These relays can switch AC or DC
loads. Two sets of eight relays each have a common. The PPC-
2062 features eight electromechanical relays.
PPC-2070 - 2073 Digital In Modules
Up to four modules of this type may be added to a PPC system.
Each module includes either 8 or 16 discrete inputs. The PPC-
2070 and 2071 modules accept 120Vac signals. The PPC-2072
and 2073 modules accept either 24Vac or 24Vdc.
PPC-2000 Terminal Boards
The following sections describe the terminal boards that
support field I/O connections to some modules.
PPC-AITB-1 Analog Input Terminal Board
The AITB is a compact field wiring interface for all analog
input modules. The AITB includes terminal blocks and
removable keys used for different types of inputs such as TCs,
RTDs and linear signals. For more information on these
signals, refer to PPC-KEY-01 through 04 in Table 1.1 on page
5. The keys allow easy configuration of the terminal block for
different types of inputs on different channels. The AITB is
DIN rail or panel mount compatible.
