I-8080 Counter/Frequency/Encoder Input Module, 4/8-ch Blue Cover

I-8080-G CR is a high-speed Counter/Frequency/Encoder input module from the I-8K/I-87K low profile range. Each channel can be configured for up counting, frequency measurement, up/down counting or direction/pulse counting, so one module covers a wide range of counting and timing tasks.The module accepts both isolated and non-isolated (TTL) input signals. A programmable low pass filter from 1 to 32767 µsec lets you suppress noise on the input lines, and a power and communication LED shows module status at a glance.Typical uses include counter measurement, frequency measurement and encoder-based motion control. The gray-cover variant is the one listed under this ordering code.ApplicationsCounter measurementFrequency measurementEncoder motion control

I-8084W-G is a counter, frequency and encoder input module from the I-8K/I-87K High Profile PAC I/O series. It provides 32-bit hardware counting and frequency measurement on eight isolated input channels.Each channel can be set to a different mode, so one module can use some channels as Up Counters and others as Frequency or A/B Phase inputs. The supported modes are Up Counter, Frequency, Up/Down Counter, Dir/Pulse Counter and A/B Phase Counter, with the bidirectional and encoder modes available on four channels each.Typical uses are counter measurement, frequency measurement and encoder-based motion control. A programmable digital filter from 1 to 32767 μs can be applied to the inputs, and the minimum pulse width is 2 μs.ApplicationsCounter measurementFrequency measurementEncoder motion control

The I-8088W-G CR is a PAC I/O module that combines 8 wet-contact digital inputs with 8 PWM outputs. The PWM waveforms are generated by hardware, so the outputs run without software intervention once configured, which suits control tasks that need a stable duty cycle and frequency.Each PWM channel offers a frequency of 10 Hz ~ 500 kHz (non-continuous) with a duty cycle of 0.1 ~ 99.9 %. Channels can be started individually or together, and burst mode is available for standby operation. Digital input channels can be used either as simple inputs or as the hardware trigger source for the PWM outputs.The PWM outputs are TTL-type, source-configured, with a stated load of 1 mA at +5 VDC, so the downstream circuitry should be checked against these ratings. The digital inputs are rated for +5 ~ +30 VDC ON level and provide 3750 Vrms intra-module isolation.Hardware-generated PWM outputs, without software interventionSoftware and hardware trigger modes for PWM startIndividual or synchronous PWM output on all channelsBurst mode for standby operationApplicationsControlling the position or speed of motorsDimming the brightness of lampsControlling the speed of fans

The I-87082W-G CR is a two-channel counter and frequency input module for engineers who need high-speed pulse counting or frequency measurement within an I-8K/I-87K PAC I/O system. Each channel can be set up for counter or frequency operation, with 32-bit counts and inputs up to 100 kHz.Each input can be chosen as isolated or non-isolated to suit the signal source. Isolated inputs provide 3750 Vrms isolation and accept ON levels from +3.5 VDC to +30 VDC. Non-isolated inputs use a programmable threshold between 0 and +5 VDC. A programmable digital filter and a low pass filter help reject noise with pulse widths shorter than the minimum high or low width.Two sink-type open-collector outputs provide programmable alarm signalling, and the module includes an RS-485 port using the DCON protocol. A dual watchdog, with a 1.6-second module watchdog and a programmable communication watchdog, adds supervision for unattended installations.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment
