| Description
This is another member of the 2600 series of smart I/O modules which connect to an Ethernet via a 2601 communication module. It can read or write to 48 digital I/O lines. The 2610’s microcontroller provides I/O services to a remote client such as model 2601 via a category-3 cable. The cable supplies isolated serial communication and power to the 2610’s microcontroller. Switch de-bounce
The 2610’s microcontroller uses a 10 millisecond de-bounces filter on all digital input lines. This minimizes errors from electromechanical switch bounce
Interlocks
Up to five independent interlock circuits and/or emergency stop circuits can be threaded through the 2650 relay and 2610 digital I/O modules. Each digital output can be jumper programmed to open when an interlock voltage is removed.
Peripheral Modules | Model 2601 | Communication module | | Model 2608-0 | 16 analog and TC inputs (16 bit) | | Model 2608-4 | 16 analog and TC inputs (16 bit), 4 analog outputs (16 bit) | | Model 2608-8 | 16 analog and TC inputs (16 bit), 8 analog outputs (16 bit) | | Model 2610 | 48 digital I/O, 5VDC to 24VDC | | Model 2620 | 4 encoder/counter/frequency interfaces (32 bit) | | Model 2650 | 8 relay outputs, 0V to 240V @ 10A | | Model 2652 | SSR I/O Module (Supports 8 SSRs) | | Model 2653 | SSR I/O Module (Supports 16 SSRs) | | Model 204 | Power supply, 24 VDC @ 5A |
Field Wiring
The 2610 has forty-eight RJ-11 jacks for direct connection to field wiring. Each jack supplies interlocked power and connections for up to three digital I/O channels. Two of the three channel connections are repeated in adjacent jacks. This allows connecting an I/O cable that has three signals to a single RJ-11 jack as shown in Figure 3. Pulse Width Modulation
The first eight output channels may be programmed to produce pulse width modulated outputs to control electric heaters, flashing lights, etc.
Status Indicators
The 2610’s microcontroller can monitor and report the state of each I/O line. Each line is monitored with an LED that lights regardless of whether the channel is driven by an external signal or by the channel’s output driver. See Figure 3.
The 2610 has a RESET LED that flashes briefly after a software reset. There are also XMT, RCV and LINK indicators that show communication with the communication module. A heartbeat LED flashes at two second intervals to indicate that the 2610 is function properlyNon Ethernet System
Figure 4 shows a low-cost system using an RS-232/422/485 serial port in place of an Ethernet port. It uses a 2699 adapter board connected to an I/O module. The adapter converts RS-232/422/485 signals into a format compatible to the I/O module. The adapter board requires 24 volt power. Windows SDK
A Windows DLL for the 2600 series is provided at no additional cost. It requires the use of a 2601 communication module in addition to the 2610.
The Windows 98/NT/2000/XP DLL is a common interface for the entire 2600 series. The SDK includes sample programs for Visual Basic and C++. The source code for these programs show how to use the DLL. A second DLL is provided for systems that use the 2699 serial port adapter.
