Product Description:
Bosch Rexroth manufactures the control board BTA20.4-NA-DB-VB-BS as a part of the BTA20 series for industrial automation. Its INTERBUS adapter integrates all active electronics on a single PCB and it supports 3-word I/O width with 8 isolated digital inputs as well as 8 outputs for connecting external devices.
The BTA20.4-NA-DB-VB-BS board is compatible with 24V input signals and has a current consumption of less than 10 mA while each output can source up to 200 mA at 24V DC. Its integrated converter connects an RS232 control interface to an RS422 terminal to eliminate the need for an additional interface board thus ensures simple and reliable communication with operator terminals through RS232/RS422 and INTERBUS. The BTA20.4 board’s interface has a baud rate of 0 to 38400 and it receives RS232 signals between ± 5 to ± 12 V while the RS422 output provides 0 to 5 Vdiff with a 60-mA current limitation. The interface module has a +5 V bus source to power other devices. The BTA20.4 board has IP65 protection on the front panel and has an operating temperature range of +5°C to 45°C along with a storage temperature range between -20°C to 60°C at an attitude of 1500 m above sea level.
The BTA20.4-NA-DB-VB-BS board operates with 18 to 30 V source, it has a rated power consumption of 18 W and utilize 1 A of current. The size of the unit is 407 x 169 x 119 mm and possess a mounting dimension of 375 x 137 x 119 mm. The BTA20.4 board weighs approx. 2.1 kg and shows compatibility with BTV20.3 and BTV40 terminals. It features safety circuits and is painted light grey with standard RAL 7035 for weather proofing.
