Features:

  • Combines field I/O circuits and tachometer signal processing for communication with the SNAT 603 CNT.
  • Supports DDCTool connectivity through plastic optical fibers and works with optical distributors for multi-drive installations.
  • Operates with 24 V DC or 48 V DC input, provides up to 10 A output current, and withstands temperatures from -40°C to +85°C.
ABB SNAT609TAI provides an effective interface between field devices and the drive control system by collecting digital, analog, and tachometer signals before forwarding them to the controller. The board simplifies wiring through dedicated flat cable connections and supports stable communication within DDC drive systems. Its combination of I/O handling and tachometer processing makes it suitable for industrial automation environments where accurate signal transfer is essential.

The board is intended for use with SNAT 602 TAC, SNAT 603 CNT, and DDCTool communication hardware. Field wiring is terminated on the SNAT 602 TAC terminal block board, while optical communication with a personal computer is achieved through the SNAT 606 CMT or SNAT 608 CMT interface board. Different optical fiber options allow installation distances to be matched to application requirements.

ABB SNAT609TAI is also well suited for applications requiring centralized drive management. Multiple drives can be connected to a single PC by using compatible optical distributors, while longer communication distances can be accommodated through glass fiber installations with a YPC 115 A interface. With support for 9 digital inputs, 3 digital outputs, 1 analog input, 1 tachometer interface, and an operating temperature range from -40°C to +85°C, the board provides dependable performance for industrial drive control systems.

The SNAT609TAI ABB Tacho & I/O Interface Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
ABB SNAT609TAI serves as the tacho and I/O interface board for the drive control system, bringing together field I/O signals and tachometer signals before forwarding them to the SNAT 603 CNT. The board includes the required I/O circuits for SNAT 603 CNT and connects through a 36-pole flat cable, creating a reliable interface between the controller and field devices.

Field I/O signals together with tachometer signals are first connected to the SNAT 602 TAC terminal block board and then transferred to ABB SNAT609TAI through a 40-pole flat cable. The same SNAT 602 TAC terminal block board can be used for connecting I/O signals either to APC or to ABB SNAT609TAI on the DDC drive, although the signal names and terminal connections differ when used with the interface board.

ABB SNAT609TAI also supports optical communication for DDCTool by working with the SNAT 606 CMT or SNAT 608 CMT board installed in a personal computer. A pair of optical fibers connects the PC interface board to the interface board. Plastic fibers can be used for distances up to 15 m with standard attenuation cable, while extra low attenuation cable extends the distance to 25 m. For longer connections, glass fibers are required.

When several drives need to be controlled by one PC, the optical distributor YPC 111 A is used with plastic fibers, while YPC 115 A supports glass fibers. Because ABB SNAT609TAI includes receiver/transceiver circuits V10/V11 for plastic fibers only, glass fiber installations require a YPC 115 A near the interface board. Operating with a 24 V DC or 48 V DC input, the board provides a rated 24 V DC output, supports up to 10 A output current, and offers 9 digital inputs, 3 digital outputs, 1 analog input, and 1 tachometer interface across an operating temperature range of -40°C to +85°C.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why does ABB SNAT609TAI work with SNAT 602 TAC?
SNAT 602 TAC serves as the terminal block board where field I/O and tachometer signals are connected before they are transmitted to ABB SNAT609TAI through a 40-pole flat cable.
How does ABB SNAT609TAI communicate with a PC?
Communication is established through a SNAT 606 CMT or SNAT 608 CMT board installed in a personal computer. A pair of optical fibers links the PC interface board to ABB SNAT609TAI.
Can ABB SNAT609TAI support multiple drives from one PC?
Yes. When one PC controls several drives, ABB SNAT609TAI works with the YPC 111 A optical distributor for plastic fibers or the YPC 115 A for glass fiber networks.
Does ABB SNAT609TAI support glass fiber connections directly?
No. ABB SNAT609TAI includes receiver/transceiver circuits for plastic fibers only. When glass fibers are required because of longer transmission distances, a YPC 115 A must be installed near the board.
