Block 24 VDC 8 In/8 Out Module:

• Provides eight output points and eight input points
• Eight point output section:
• Sources voltage for individual loads from a DC power supply
• The external supply is nominally 24 volts, but can be between 20 and 30 volts
• Eight LEDs near the field terminal connector of the module indicate the logic state that drives each output
• An LED labeled SC lights if any output attempts to drive a short circuit
• Eight point input section:
• Converts DC signals from devices into logic levels that the CPU can use
• Each signal is converted into a corresponding logic 1 or 0 which is transmitted through the communication interface to the CPU module
• An “on” signal is nominally 24 VDC, but can be any level between 15 and 30 volts
• An “off” signal is any level below 5V
• Wiring configurations may be sink or source
• Eight LEDs near the field terminal connector of the module indicate the logic state of each input

Block Output Stepper/Input Encoder/ Input 24 VDC Module (2/2/2 Channel):

• Two output stepper channels:
• Each channel can control one stepper drive
• Maximum step rate is one million steps per second
• An external power supply (4.5 VDC to 20 VDC) or the internal +5 VDC can be used to power each stepper output
• Commands and control data are sent to the module, and status and position information are received from the module, via software
• Two input encoder channels:
• Each channel can interface to one independent quadrature incremental encoder or equivalent device
• Information from each encoder is used to update a separate position counter and latch within the module
• For each channel, a 24-bit counter is incremented or decremented based on signals it receives from the A, A, B, and B; outputs of a quadrature encoder
• The counter value can be latched (stored) if the module receives an I or I output signal from the encoder 
• Two 24 VDC inputs:
• The 24 VDC inputs convert DC signals from devices into logic levels that the CPU can use
• Each signal is converted into a corresponding logic 1 or 0 which is transmitted through the communication interface to the CPU module
• An “on” signal is nominally 24 VDC, but can be any level between 15V and 30V
• An “off” signal is any level below 5V
• The wiring configurations may be sink or source
• Two field-side LEDs indicate the state of the inputs
