Sales of programmable logic controller (PLC) I/O modules are up "quite strongly after the recession," with double-digit growth in both 2010 and 2011, whiles sales of distributed control system (DCS ) I/O was somewhat slower, according to IMS Research.
I/O modules, which are mostly used with controllers, are essential components in complex industrial automation systems. By adding more I/O modules, the scope and flexibility of an entire automation system can be enhanced, saysIMSmarket analyst Alex Hong. PLCs, for example, can move towards their control capability to the field level by adding remote I/O modules.
该市场有许多活跃的供应商,包括作为一系列自动化产品和专家的供应商,主要提供I/O模块。从广义上讲,I/O模块可以按控制器类型(PLC,DCS和Industrial PC)分为三类,这是工业自动化中最常用的产品。Hong说:“全球衰退损害了工业自动化市场,从2008年到2009年,每种控制器类型的市场下跌了20%以上。由于对控制器产品的需求降低,I/O市场也下降了。”但是,“自2010年以来的复苏非常令人兴奋。由于整个I/O模块市场从控制器市场的回收中受益,尤其是对于PLC而言。”整个I/O模块市场在2010年增长了20%以上,在2011年又增长了10%以上。增长的主要贡献来自PLC I/O模块,因为开花机构建机市场。
机器建设者市场,尤其是在欧洲和亚洲,是I/O的大买家。Hong说,由于他们使用PLC广泛使用,因此对PLC的I/O模块的需求显示出强劲的增长。“另一方面,对流程自动化的需求有所落后。这些项目的现金流量由于经济衰退而被切断,这种情况甚至持续到2011年。对于PLC I/O模块而言,该过程行业的增长速度要慢。”
