rs-485 i/o modules features introduction the ADAM-4501/4501d consists of compact-sized ethernet-enabled communication controllers with a x86 cpu architecture. they support not only an ethernet interface but also 4 serial ports, which makes them very suitable for industrial communication and control applications. the ethernet-enabled features include built-in http server, ftp server and email alarm functions. the modularized i/o design provides high fexibility for versatile application requirements. the ADAM-4501/4501d also supports rich modbus function libraries including modbus/rtu (master/slave) and modbus/tcp (server/client) function libraries. 10/100base-t ethernet interface email alarm function built-in web server built-in ftp server and client supports versatile i/o modules full functions of standard tcp and udp sockets optional 4 digit 7-segment led display supports modbus/rtu and modbus/tcp function libraries 1.5 mb flash rom/640 kb sram 4 serial ports available integrates all operations in windows utility ? ? ? ? ? ? ? ? ? ? ? specifcations general connectors 1 x rj45 (ethernet) 1 x rj48 (com1) 2 x plug-in terminal blocks (#14 ~ 28 awg) indicators leds for power, run, communication and battery power input unregulated 10 ~ 30 v dc w/power reversal protection system cpu 40 mhz, 16-bit cpu power 4 w @ 24 v dc consumption memory 1.5 mb fash memory: - 256 kb system fash disk (drive c: read only) - 256 kb fash memory (accessed by function lib) - 1024 kb fle system, 960 kb for user applications (drive d: read/write) 640 kb sram, up to 384 kb with battery backup (accessed by function lib) real-time clock (rtc) yes watchdog timer yes input/output digital input channels: 4 dry contact: logic level 0 : close to gnd logic level 1 : open wet contact: logic level 0 : +2 v max. logic level 1 : 4 v ~ 30 v digital output channels: 4 open collector to +30 v, 30 ma max. load power dissipation 200 mw ? ? ? ? ? ? ? ? ? ? ethernet-enabled communication controller with 8-ch di/o ethernet-enabled communication controller with 8-ch di/o and 7-segment led communication lan 1 x 10/100base-t rs-485 speed 1.2 to 115.2 kbps serial ports com1: rs-232 (full modem signals) com2, com3: rs-485 com4: rs-232 (programming port)/rs-485 (selected by jumper) software c library borland c++ 3.0 for dos operating system rom-dos environment humidity 5 ~ 95% rh operating temperature - 10 ~ 70 c (14 ~ 158 f) storage temperature - 25 ~ 85 c (-13 ~ 185 f) ordering information ADAM-4501 ethernet-enabled comm. controller w/ 8-ch di/o ADAM-4501d ethernet-enabled comm controller, 8-ch di/o, led ? ? ? ? ? ? ? ? ? ?
